I don't want to be rich, for me being free on my (an my family's) current standard of living is enough. I live in Eastern Europe (Hungary) and my current net income is $24000 per year. $30000 per year would be enough. (It is a very strong middle-class level here, maybe I can say upper-middle class especially if you don't have debts and already have a reasonable house.) I am 35 years old and let's say I want this money to last until I am 80. So I need $1.350.000. Provided that I will most probably always be a single founder and most probably will always bootstrap because no one will want to give me money, it will be enough to sell my company at $1.350.000, which I think would be more than doable if I would succeed with my current idea. Edit: and also it is hard to imagine that I would absolutely not make any income with the lots of fun-projects I would do after my 'retirement'.
