Russ, I had a hand injury (I probably already told you about it) when I was in my late teens...got cut with a knife during a donnybrook, and very nearly lost the baby finger of my left hand. As many years as it was ago, I still don't have complete feeling, especially from the middle knuckle to the tip...I had to scrap playing guitar for quite some time, and fortunately the surgeon who re-attached the finger, did more surgery later on and re-attached the tendons in such a way that my finger has a slight curvature and is in the proper position for playing keys. Still have trouble on guitar, especially barre chords.
So, I concentrate on keyboards today...the arranger is my friend...my left hand is much stronger, but an evening of all solo piano (especially a lot of left hand bass work) makes it ache, and even with therapy, it will never be as strong as I'd like. Hence, again, the arranger.
Used to hate using it at first, but today's arrangers don't sound as robotic and phony, and the styles are so much better than the old PS-6100 I started on...yeeech!
You'll find your way...I know what you mean about "not good enough to satisfy yourself", but, you shouldn't deny the listener the chance to hear your talent...you are a fine player to my ears.
Good luck,
Ian
