Every manager has a dramatic increase in effectiveness when he controls his money. Musk, Brin, Bezos, and Zuckerberg own most of their companies, and they don’t have to do a quick “bubble crack” while they’re in the caregiver – they’re all theirs and they’ll be in 5 years. And the brains and aspirations are enough to measure whose rocket flies into space more times, and not whose car and villa is more. Some with $100 million will simply strive to get $1 billion, while others will live on $100,000 and think what is interesting, useful and really cool to do. There is no need for money to do something. Money is needed to do nothing.
