I'd change my lack of ability to play guitar. I spent my money and a beautiful shiny black acoustic that I love, it even smells wonderful! But I suck. Wheneve I try to practice I just get mad because I suck so much. I took lessons for a year and now I can only play 'Ode to joy'.
Feel my pain! I've even tried to appease the gods of music by offereng gifts but it hasn't helped. They don't like me.
