It's not about hard work, it's about how much of who you are must be devoted to the career. I work very hard at a 400 person company. but I get to go home after about 42-48 hours a week and enjoy being me. That involves chess, guitar, politics, and billiards. Founders and ground floor engineers ARE the business, the code, and the company.
