I actually wonder how common it is to retire early? First of all what is "early"? If it is before 65 then a good number of people do.

Getting to the spirit of the article though, a good chunk of the people that I know who don't "have to work" anymore, don't, or do so infrequently. I think it is rare indeed for someone to become a billionaire or hundred-millionaire without the manic drive that this article speaks of, but I do know plenty of millionaires who either don't work or take it very easy.

It actually would make sense that a lot of millionaires wouldn't work anymore. Presumably they make most of their money in a one-time deal (i.e. their company gets sold), if they were a solid software engineer, etc at said company it might not seem worth it to go back and work another company doing CRUD. Maybe the right opportunity comes along, maybe it doesn't, but why pressure yourself if you don't "have to work".
