Zen master Genpo Roshi said, "Don't ask if you're stuck, ask where you're stuck". Life is so much more interesting when you notice that, no matter where you are, you're stuck. You may be beautifully stuck, ecstatically stuck, despondently stuck or even transformatively stuck. It doesn't really matter. Ask yourself "Where am I stuck?" at least once a day and you'll be in line with directive #14 of the manifesto:

14. Don’t be cool.
Cool is conservative fear dressed in black. Free yourself from limits of this sort.

I'll bet you're terrified to write (or even play) a song that sounds like anything on this list. If so, your cool is showing and that's where you're stuck. Write what needs writing and let someone else worry about whether it's hip.
