“Being up all weekend, working for huge stretches without sleep and then sleeping on the office floor!” Sounds familiar?

Well, that’s how the American business mogul, co-founder of Microsoft Corporation, Mr Bill Gates started out his ‘Fero’. Developing operating systems and softwares such as Windows and MS office were not an easy task for him.

As a workaholic in his past, Gates liked to work in “Coca-Cola-fuelled” late-night sessions and crack codes, with his mate Paul Allen, co-founder of Microsoft.

“He’d be in the middle of a line of code when he’d gradually tilt forward until his nose touched the keyboard. After dozing an hour or two, he’d open his eyes, squint at the screen, blink twice, and resume precisely where he’d left off – a prodigious feat of concentration” Paul Allen recalled.
