Musicians approach their music with various personalities and intentions. To succeed at music it’s important to figure out your “why?” Do you simply love to play and create? Does the creative process stifle you, but you go through it so that you can play live shows?
I think most of our blocks in life exist because we are unable to assess our strengths, our passions, and our weaknesses.

If you want to race, winning will require a lot more sacrifice.
Maybe you just like running.
