I'll be 60 next month. Whatever you do, don't judge yourself by the skills and talents of others. I've never had the ability to play the fast parts that people who have that knack can. I can enjoy rhythm guitar with an embellishment here or there and am not in it for competition. I started playing bass guitar in 1977 and seem to do much better with that, but guitar has always been a challenge to play with speed. So, I play within myself. If it were easy for everyone there wouldn't be any stars at it.
