Sorry, re-reading my comment, I didn't actually say it, but I agree that we need more data - I just meant we do have some data (with the privisos I noted). Regarding Google-millionaire data: what percentage actually does keep working? We hear about those who do, but not of those who don't (eg Minecraft's Notch). "Newsflash: multi-millionaire relaxes" And, confounding factor: people who succeed amazingly well often keep doing whatever made them wealthy, well beyond financial satisfaction. At least, one hears of those cases - I don't actually know the percentage of how often, vs. those who take it easy. [Guess this is what brbsix meant] Anecdatum: when I made enough from something I created, I quit. Yet, turns out I was happier before... so was probably a mistake to quit.
