Why do I suck now (20 characters)?

I used to be good at sculpture. I made a few fairly intricate sculptures when I was much younger. I never had any training or anything - just came naturally. Recently one of my sculptures broke, and I figured I would try to recreate it. Man, was I in for a surprise. My new creation looked like - well it looked like a lump of clay. Hehe.. not exactly the masterpiece I had in mind. So why do I suck now? Granted I haven't been practicing, but I never did practice before I made the original one either.
