I would love to trade my day job to play drums full time making the same exact living I make right now. I used to want the rockstar mansion and the five Ferraris in the driveway but thats not a measure of success to me anymore.More than anything thats a measure of that guys lucky break. There is no clear path to that kind of life, otherwise we would all have it. Jack Welch who became CEO of General Electric did not go to CEO school. He was/is a chemical engineer by degree. You have to be prepared for that big break when and if it comes your way. I am not a rockstar in that mansion, but I have no regrets what so ever, and I am proud to call myself a drummer.But if you love drums unconditionally, you will have a happy life just playing local gigs and living modestly, and being able to legitimately call yourself a full-time musician.
