Books, personal assistants and gadgets are some of the things that the world's most powerful and influential business people admit they cannot function without.
Featured on job networking site LinkedIn, the full list resulted after questioning more than 50 influential people, according to News.com.au.
While Virgin king pin Richard Branson insisted that having an assistant who is on the ball 24/7 is one of the main ways he stays on top of business while Hewlett-Packard CEO Meg Whitman makes sure that she always carries her laptop (HP Envy x2), swimsuit and country music when travelling to focus, tune out and stay flexible.
Branson admitted that he'd be hopelessly lost without his personal assistant Helen.
And Whitman asserted that she always carry a swimsuit while travelling and try to stay at a location near a pool so she can get in a morning swim regardless of time zone.
Things that Indian-born American physician Deepak Chopra said he just can't travel or work without: "Mybasis, Dream Weaver, and my iPhone and iPad in my toolkit."
His mybasis acts as his online personal dashboard recording information about his body, while his Dream Weaver helps him relax and his iPad keep him connected to family, office and friends, something he asserted is important to him.
But Peter Guber, CEO of Mandalay Entertainment and owner of Golden State Warriors and Los Angeles Dodgers, can't function without his smartphone, which he admits he's addicted to.
The author also revealed that he's gone back home to get his phone if he's forgotten it but not his wallet.
Unlike others Vivian Schiller, Chief Digital Officer at America's NBC News said he carries almost nothing.
Neil Weinberg, Editor-in-Chief at American Banker, said he has learned to stay away from his smart phones and laptops as far as possible after he realised it was raising his blood pressure and stress.
Now, he usually carries only a book while travelling.
Meanwhile Clara Shih, CEO of Hearsay Social and Author of The Facebook Era, insisted that being on the go as head of a fast-growing tech company means she can't be without her Droid 4 (phone), her Tory Burch ballet flats and one business card with an important reminder: to slow down and take a deep breath.
Interestingly, RedBalloon founder Naomi Simson said she never gets by without a smile.
Jennifer Dulski, President and COO at Change.Org simply can't live without her calligraphy pens because she finds that a handwritten personal note can be especially precious.
But Craigslist.com founder Craig Newmark insisted that he couldn't function without his Samsung Galaxy Note II which he uses 80 per cent of the time.
