I, for one, am actually still incredibly idealistic, and I still can credibly or very strongly believe that you have to keep fighting for what you believe in, because it's only when you stop that you've truly lost.
All I want to know is that I can keep this house for the rest of my days and I want to make good music... and have the odd sports car in the garage, obviously!
I just throw it out and see what happens. If it sounds and feels right, then I continue.
