Lord Alan Sugar doesn't lose any sleep over firing candidates on 'The Apprentice'.
The 67-year-old business magnate has confessed he doesn't fail to get a good night's sleep after sending potential future partners home on the BBC One reality series because he claims they bring it on themselves.
Quizzed on whether the friction in the boardroom ever keeps him awake at night, he said: "I don't have any sleepless nights, no. It's friction amongst them isn't it? It's not friction for me."
And Lord Sugar's right hand man Nick Hewer - who along with Karren Brady follows the candidates as they attempt to complete various business tasks in a bid to win a £250,000 investment - certainly hasn't been losing out on sleep either, as he's admitted it was exhausting trying to keep up with all 20 of them.
Referring to the decision to have 20 candidates rather than the usual 16 in celebration of the 10th anniversary, Nick said at 'The Apprentice' launch at London's Ham Yard Hotel: "It makes life very difficult for those following them. When you try and follow ten people for three days, writing about everything and everything everybody says to everybody else and trying to work out whether it's honest, the reactions honest. It's tough.
"Please don't do it again."
Agreeing with Nick, Lord Sugar added: "I don't think we'll be doing it again next series. Maybe for the 20th anniversary."
'The Apprentice' series 10 kicks off with a double bill on Tuesday October 14 followed by a second episode on Wednesday October 15, after which it will air on Wednesdays at 9pm.

Mark Wright has nominated his fiancée Michelle Keegan and his "dopey" cousin Elliot Wright to lip-sync for charity.
The former 'The Only Way is Essex' star has joined a host of celebrities who are raising money for the new charity, Global's Make Some Noise - which aims to improve the lives of disadvantaged children and young people across the UK.
Mark has encouraged people to donate to the cause by filming himself lip-syncing along to the public's favourite tunes.
The 27-year-old television personality and radio presenter decided to nominate three of his nearest and dearest to also lip-sync for Make Some Noise, before launching into a rendition of Enrique Iglesias's song, 'Hero'.
He told the camera: "I nominate my big cousin Elliot Wright because growing up as a kid he was my hero, but not any more because he's a big dope. My fiancée Michelle because she is my hero for coming into my life.
"Zoe Hardman for sitting in for me on a Saturday night as I do 'Strictly Come Dancing'. She's my hero too. This song is for you guys."
Other celebrities participating in the fundraiser includes: Union J, Emma Bunton, Jenni Falconer, Jamie Theakston and Jason Donovan.
The public are encouraged to get involved themselves by recording a lip-synced video and nominating their friends to get involved and start donating to the worthy cause.

The cast of 'Downton Abbey' are to guest star in Disney's 'Doc McStuffins'.
Stars of the ITV period drama including Joanne Froggatt (Anna Bates), Lesley Nicol (Mrs. Patmore), Matt Milne (Alfred Nugent), Nigel Harman (Mr. Green) and Robert Bathurst (Sir Anthony Strallan) are among the guest voice cast for an upcoming special episode of the Emmy-nominated Disney series.
'Doc McStuffins' tells the story of a young girl (Doc) who runs a clinic for her stuffed animals and toys out of her backyard playhouse as part of her aspiration to become a doctor like her mother.
In the extended length episode titled 'Let the Nightingale Sing' Doc and the toys will magically travel back to 19th Century England where they meet a young Florence Nightingale, voiced by Joanne Froggatt, and help her realise her dream of becoming a nurse.
Alongside Joanne as the famed "Lady with the Lamp", Lesley will take on the role of miniature porcelain doll Pip, Matt will voice Bernard the teddy bear, Nigel will play tin rooster Doodle Doo and Robert will become Admiral Fiddlesticks.
'Let the Nightingale Sing' will feature a new original song titled 'Love What You Do' and is to premiere on Disney Junior in the UK this December.

Neve Campbell is pregnant with her second child.
According to Us Weekly magazine, the 'Scream' actress is expecting a baby with her boyfriend, 'Captain America' actor JJ Feild, with whom she already has a two-year-old son, Caspian.
A source close to the couple told Us Weekly: "They've always wanted more than one child. They want Caspian to have a sibling."
The 40-year-old star - who also appeared in the television series, 'Party of Five' - is notoriously private about her personal life, but has previously spoken about her decision to name her son, Caspian.
Talking on 'The Talk' in December 2012, she shared: "We looked through a lot of books and I liked the idea of an unique name. I like having a unique name - it's [my mum's] maiden name, Neve - and not a lot of people have it.
"It's nice having something special and different and so I wanted something like that for our son."
Neve and JJ first started dating in 2011, following the actress' divorce from the Canadian actor, Jeff Colt in 2010.

Daniel Radcliffe finds it hard to deal with crying fans.
The 25-year-old actor admits it can be a regular occurrence for admirers of his to burst into tears when they meet their idol from the 'Harry Potter' films and he still doesn't know what he should say to them to calm them down.
In an interview in As If magazine, he said: "There have been times when I've met someone, and it's been awkward, and I don't know why, and someone will say to me, 'Daniel, they were nervous to meet you!' Of course, that thought never entered my head!
"The worst is when people cry though. It's an awful feeling, particularly when they are 13 or 14-year-old girls. I feel horrible that they're crying. It's not worth crying about. Please! They are mostly crying out of excitement, but I still don't know how to deal with that."
Radcliffe - who can currently be seen in 'Horns' - is adamant that he is just a "regular" guy, even though he has been an actor from the age of 10 and played the most famous fictional wizard in the world.
He said: "I hope one of the things that surprises people when they meet me is that I am really quite normal. At least I think I am! I don't think I'm an obnoxious d**k, and I think some have that perception of people who've grown up in the spotlight. I obviously know that my experience isn't the same as everybody else's, but when I talk to people, I don't feel separate from them in any way ... The aura of fame is bull-s**t. People who enjoy being treated differently and revel in the attention that others give them are generally people I don't like very much."

Justin Bieber has shaved off his moustache.
The 20-year-old singer - who had also been sporting lip hair and an attempted goatee in recent months - took to Twitter today (07.10.14) to show off his clean-shaven makeover to his 55.4 million followers.
Along with a photo of his new baby-faced look, he posted: "Shaved the monster".
Along with his facial hair, it seems the 'Boyfriend' hitmaker is also trying to clean-up his act after recently admitting plans to ditch the booze and get his music career back on track.
A source said: "Justin has been boasting to his friends about his new healthy lifestyle.
"He no longer drinks and has stopped eating junk food, too. He's had a difficult few months and is hoping that this will give him a fresh start."
The star is also reported to have started seeing £600-an-hour therapist, John Kenton, at a clinic in Los Angeles to help him keep his impulsive behaviour in check following multiple run-ins with the law earlier this year.
A source said: "Kenyon's treating Justin in person, when possible, then over Skype when he's away. Sometimes they even have more than one session a day.
"It's too soon to tell if it's having a positive effect , but the fact that Justin has kept it up and passed the first batch of sessions speaks volumes.
"If he hates something he's not normally the kind of person to stick it out."

Sarah Harding is considering freezing her eggs.
The 32-year-old singer - who recently split from boyfriend Mark Foster - always hoped to become a mother in her late 20s and is thinking of taking steps to preserve her fertility until the time is right to have children.
She said: "It does get harder to see other people have something that you want. I've even got to the age now where I occasionally find myself wondering, 'Do I need to start thinking about freezing my eggs?'
"I do feel my biological clock is ticking and while I'm not ready right now, I do want to be a mum one day.
"My mum was 39 when she had me and I'd always hoped to start a family before that.
"I still have a few years to go but I do go through stages where it plays on my mind."
Sarah's former Girls Aloud bandmate Nadine Coyle became a mother for the first time in February and the 'Call the Shots' hitmaker was stunned by the changes in her friend when she went to visit her and daughter Anaiya.
Speaking in the new issue of HELLO! magazine, she said: "I really wanted to hold Anaiya but Nadine had her clamped to her the whole time and wouldn't let her go. She's a complete earth mother, which surprised me. But I'm delighted for her."
Sarah called time on her two-year relationship with Mark in September and she says they broke up because they waned "different things".
The 'Biology' hitmaker - who first dated Mark when they were teenagers - said: "I think you have to take something from every relationship and in the case of me and Mark, I learned that going back isn't always the way forwards.
"We're very different people now to who we were when we dated all those years ago. We want different things.
"It's taught me not to expect the world from every relationship and to live in the present more."

James Bond villain Geoffrey Holder has died.
The Trinidadian actor, who was best known for his role as Baron Samedi 007 film 'Live and Let Die' passed away on October 5, 2014, aged 84.
A family spokesperson revealed that Geoffrey died in his New York home after complications caused by pneumonia. He is survived by his wife, Carmen de Lavallade and their son, Leo Anthony Lamont.

Following the announcement of his passing, Samuel L. Jackson took to Twitter to mourn the star. He wrote: "I brush up against Fame all the time, but encountering GREATNESS is Rare! RIP Mr Holder!! (sic)"

Helen Flanagan dreams of acting in 'Romeo and Juliet'.
The ex-'Coronation Street' star has named the Shakespeare play's female protagonist the character she would most like to play.
She told The Sun newspaper: "I am such a romantic. I would really, really love to play Juliet - it's my total dream role."
However, the 24-year-old actress - who has been dating Manchester City footballer Scott Sinclair since she was 19 - admitted she would find performing in the tale of star-crossed lovers a challenge.
She explained: "I know people will probably think it's a really weird ambition but I was actually good at Shakespeare when I was at school.
"My ultimate goal in acting is to appear in Romeo and Juliet, I love everything about it, especially the balcony scene."
She added: "Oh, I so, so want to do that. I want the challenge of it, to really push myself.
"I've never done theatre. It'll be terrifying but I know I can do it."
Despite her ambition to take to the stage in the tragic love story, the actress-turned-model - who appeared as Rosie Webster in 'Coronation Street' for 12 years - is considering continuing her studies rather than return to acting, following her departure from the ITV soap in 2012.
She stated: "I loved the show, I still do. But there's lots more I want to do. I might even go to university.
"I'd like to study something like psychology."

Kaya Scodelario misses her 'Skins' character.
The 22-year-old actress - who played troubled teenager Effy in the E4 drama - has fond memories of her time on the show and admitted she worried about landing other roles when she exited the series.
She told Time Out magazine: "Effy had been my only acting experience. I didn't know if I could do anything else. It's funny, I miss her a lot now."
The dark-haired beauty appeared in four series' and a one-off special of the teen drama, but despite playing the well-known character for several years, still felt blessed when she was offered the part of Catherine Earnshaw in the 2011 adaptation of the 1847 classic, 'Wuthering Heights'.
When asked if she felt her career was over when the hit TV show ended, she admitted: "A bit. I was so lucky to get 'Wuthering Heights'. It was such a different role. I was proving to myself that I could do it"
Since appearing in the period drama, Kaya has also been cast in science fiction thriller 'The Maze Runner' which the star confessed was difficult to film because she yearned for female company in the predominantly male cast.
She admitted: "Near the end, I flew my best friend out to Louisiana. It was actually fine. I've grown up around a lot of boys and lots of my friends are guys.
"But there were so many boys and I just needed some female company. I called her and I was like: "Bring me tampons and hairspray. I need you now."
'The Maze Runner' opens in cinemas on Friday October 10 2014.

Steve Jones has secretly wed his model fiancée.
The Welsh-born TV presenter tied the knot with Phylicia Jackson in a private ceremony held in a Mayfair library, in London yesterday (07.10.14), followed by a reception close to the city's iconic Tower Bridge.
A source told The Daily Mirror newspaper: "They are absolutely over the moon. All their friends and family are delighted for them.
"Phylicia looked really pretty in a strapless cream satin dress with a net veil fascinator. Steve looked dapper in a perfectly fitted grey suit offset with a burgundy tie."
Steve, 37 - who has previously dated Pamela Anderson, Fearne Cotton and Hayden Panettiere - is said to have popped the question to the brunette beauty with a vintage diamond ring while they holidayed with friends and family in Italy last month.
The source added: "It might seem to have happened incredibly quickly to outsiders, given that they only had a few weeks to plan the entire day, but they couldn't be happier.
"They spent two months on a road trip around Europe over the summer, which is when Steve decided she really was The One."
Phylicia met Steve while he presented the US version of 'The X Factor' in 2011 and moved back to the UK with him following his exit from the show just a year later.
Steve previously said: "I met my girlfriend in the States so it was definitely a worthwhile trip."

'Strictly Come Dancing' star Aliona Vilani is sick of having partners with "two left feet."
The 30-year-old professional dancer - who was voted off the show on Sunday (05.09.14) with her partner, 49-year-old 'Masterchef' host Gregg Wallace - is said to be tired of being paired with celebrities who lack ballroom ability.
A source told the Daily Mirror newspaper: "She feels she is due a good partner next year and is sick of being voted off early on because her partners have two left feet."
The blonde beauty won the primetime BBC competition in 2011 with McBusted star Harry Judd, but has mourned her victory after being paired with older men who are untalented in the dancing department including 70-year-old ex-golfer Tony Jacklin and 76-year-old TV personality Johnny Ball.
The source added: "Aliona is struggling to hide her disappointment. She really wants someone young and keen and with respect to Gregg, Tony and Johnny, not old and lacking dance skills."
After being voted off the show, the star appeared annoyed as she retweeted various comments in which fans said she deserved to be paired with a more talented celebrity.
However, she appeared to have no hard feelings towards her most recent dancing dud, tweeting: "Want to thank Gregg Wallace for trying his best, working really hard and giving it his best shot!"
