Cash-flow muses
nico: I don't agree much with the idea, seems like trying to take a shortcut instead of focusing on real hard work to achieve what you want.I think that "cash-flow muses" are kind of a myth. If there's something easy to do, it's probably easy for a lot of people, hence you'll have a lot of competition, and market price will be low. If you want to differentiate yourself, then you'll have to put time and work into it, and it'll stop being a cash-flow muse. Also, if you need many cash-flow muses, each taking up only a bit of your time, together they'll take up a lot of your time.Anyway, why do you want to free up your time anyway? If you'd like to focus on doing what you really want, then you should read this: http://www.paulgraham.com/love.html (a bit long but worth it).
