I'm a big fan of not giving up. I've done some damage to my hands over the years. In brief, no family, group homes and foster homes and was nervously cracking my knuckles at 10 when my bones were still developing. Then martial arts did some more damage when I started that at 16. Arthritis has been on its way for a long time. I've never been able to play proper bar chords where I lay my index finger across five or all six strings. At least one string is dead and barred 7th chords... forget about. But keep playing. Music is a mix of passion, natural gifts and practice practice practice. Most obstacles can be overcome or worked around.
