I've been through a couple of instruments, and I can't seem to find my niche.

Age 11, got an acoustic guitar. Dreamed of being Johnny Cash. Found out I can't rightly work the frets.
Age 15, got an electric. Figured, hey, maybe I can play this easier. Was wrong.
At 17, tried keyboards briefly, again not having nimble fingers is a hindrance.
18, I got my first bass. I fell in love, played it all the time.
Lately, I've fallen out of love with bass. I hoped that getting a new one would change anything, but I'm sure it won't now.
While at Guitar Center last night, I listened to all the guys trying out different istruments and I felt, well, inadequate. Discouraged, even.

I wasn't discouraged by their skill, moreso by the fact that they found their instrument, and I hadn't.
Practice makes perfect, I understand this, but I can't practice something that I can't fall in love with.
It's a matter of interest over talent.

I know I have some kind of music in my soul, but I just can't find it.

Currently, I have a harmonica, which I'll say I'm playing fairly well, but my heart just isn't in it, nor is my interest.

I'm posting this to all of you, looking for suggestions or even like stories.
Above everything else, I'm at a loss for what direction to head.

Care to lend a hand or drop some knowledge?
