Losing everything you came with.

I play the piano, but it's far from exceptional.
I play the guitar, but it's far from phenomenal.
I can sing a bit, but it's far from presentable.
I take photographs, but its far from original.

I am not gifted in any of these subjects, I just mess around with them. If I had the choice of mastering one of these things and in exchange lose the skills I have on the other three, I would.  Would you make that decision?
