I guess I qualify as a 'fool investor'. I have more (semi)passive income then I need for living, and still work (30 hours in average per month, 2012) on projects that I consider fun, earning even more. I've been self employed most of my lifetime, while most of my friends are long term unemployed, or try to make a living with short precarious works. I agree to them that most jobs are shit, and encourage them to step out of the treadmill, helping them with their problems with unemployment office and the like. Every few years, one of my friends has a business idea to become self employed, and if I think that the idea has value, I invest in them. e.g. I helped a friend to buy tools and machinery to become a self employed ship builder, and bought washing machines, desks, computers for an other friend to launch an self service laundry + internet coffee shop. I also help them in keeping the books, and filing taxes. I wrote my first accounting system at age of 13, so I know what I'm doing. My investment terms are likely the most unusual you ever encountered: I take no interest, and they are free to pay back any amount any time they want. But if they do not manage to pay back at the time my birthday is dividable by 7, then I fold all debts. The same terms applies, if I help a friend with money for bail, or tenancy deposit, and the like. I really enjoy my frugal lifestyle. I have no use for more money, besides gifting/investing it in real life friends that no bank or normal investor would even touch.
