Composer Igor Stravinsky said something to the effect of: we find inspiration through work, not the other way around.
Amateurs wait for inspiration to work; professionals get to work knowing inspiration will follow. Good advice when sitting in the practice room waiting for the muse to strike before beginning.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
