Hey, here's a few (ok, 6) cents from me, being 40 and having spent 4 years out of corporate IT in order to pursue my dream of making music for a living...
1. The story of Siddhartha is relevant, in that a life in pursuit of knowledge does not necessarily come with anything resembling success in the western sense of the word. http://en.wikipedia.org/wiki/Siddhartha_(novel
2. No one should tell you not to do it, it's your dream (myself included, for all that I'm back in corporate IT, and reassembling my studio, since I wound up selling most of my stuff over the 4 years of my adventure), I'd do it again in a heartbeat, the only question is when.
3. You'll have to carefully define what success means to you in order to get something out of this venture. If it's calculated in financial terms at the start, it's statistically unlikely you'll look back on the experience at the other end, however that comes to pass, and view it as a success.
4. Watch One Piece (anime) -I generally avoid mainstream media.
5. Study Die Antwoord -some people that made it happen; on their own terms.
6. Read the 4 agreements.
