I read that Sergey Brin might retire from Google so he can learn the blue guitar to a more accomplished degree.
It seems most rich people , or people, spend their entire lives making enough (or trying to make enough) so they can have enough security to do what they love.
It doesn't really work that way. You have to stay deep within any artistic endeavor without interruption to understand it and learn it. Why not just do what you love and then let the chips fall where they may ?
