Jensen Huang started by washing dishes and cleaning toilets, and by the age of 30 he had created Nvidia, one of the most valuable companies in the world. At the age of 17, he promised his future wife that he would become CEO by the age of 30 and kept his word. Huang has led Nvidia for 33 years since the company was founded in 1993, working seven days a week, personally managing 60 senior executives and even getting a tattoo of the Nvidia logo. Today he lost almost everything.
