Emil Barr, an entrepreneur from US worth $25 million (₹224.7 crore), has said he doesn't regret giving up sleep, friends and college parties while starting his first company. "I believe advocating for extreme work-life balance is a recipe for mediocrity," the 22-year-old added. Barr, currently CEO of Flashpass, stated he typically works "100-hour weeks" and has now optimised his life.
