You can't make a living making music any more than you can make a living making chairs. You can only make a living selling that music or those chairs. As someone who knows personally what can happen to your creativity when your focus becomes selling that which you love to make(and I am talking about the music), my suggestion is simple: Make your music without thinking about the money. Make your money any way that you can. If your money isn't a function of your music (or vice versa)you'll never get confused about the real value of music in your life.

If people want to buy something I love, I will only sell on my terms. And somethings just aren't for sale. It's like Bruce Cockburn says about love - "it only lives when you give it away". But that's just me. . .
