When I was in high school, I ran hurdles, but I was really short, so I'd barely clear them. I was pretty quick, but I had little legs, so I had to take 50 steps in between each hurdle. ↗
Rock is about finding who you are. You don't necessarily have to play your instrument very well at all. You can just barely get by and you can be in a rock band. ↗
My only general rule was to steer away from things I played with the band over the past couple of tours. I was interested in re-shaping the Rising material for live shows, so people could hear the bare bones of that. ↗
