I was diagnosed with Multiple Sclerosis in 2002 and it is just started to cause problems with my left hand. I have lost strength in my thumb and pinky finger. but I am still playing and I have a gig tomorrow night. I am not posting this to get sympathy or pity but to try to get young guitarists to appreciate their talent. My early days of playing went by in a haze because I was drunk or stoned or trying to get laid. Now that I only have a few months of playing left, I appreciate it so much more. Nothing beats the feeling if being in a smoke filled honky tonk and playing Gimme 3 Steps in front of a packed dance floor. Or being in a blues club and seeing the faces of the crowd while playing The Sky is Crying. What I am trying to say here is to appreciate your talent and dont take it for granted. Play every show as if it was tour last.
