Something is wrong....with me

I've recently noticed a little quirk of mine. Every time I try something new, that turns out to be difficult, I make up these elaborate far flung schemes that make me physically unable to do them. For example when I first began practicing Bikram Yoga I was convinced that I had crooked knees and irredeemable flat feet that prevented me from correctly performing a pose that everyone else seemed to have no problem mastering. You see it wasn't me it was biology. In Arabic class my inability to enunciate a particularly elusive deep throated sound was due to my enlarged, and I fear diseased, tonsil that I should have scheduled a surgery to remove eons ago. And in fact by attempting to make this sound was bringing on a case of dormant strep throat. Naturally this must be the reason. I wonder if try to play the piano will I soon discover that my index finger on my left hand is woefully misshapen and abnormal therefore ever preventing me from being a virtuoso. I'm no quitter you see, I'm just handicapped...in my head.
