Best advice I can give....never stop learning. Why? Because the new stuff you learn opens up new pathways to new ideas, new ways of thinking and helps you adapt and evolve. I mean if my guitar playing doesn't inspire you to want to pick up a 6 string and show me how to really play it, I don't know what will.
Oh and don't tell anyone about my Star Wars comic book habit please. Let's just keep that between us whatda say?
