Tell me about marble sculpting

I really want to start marble sculpting (or I suppose any other type of stone for that matter). Anyone know anything about it? I am afraid once I get a chunk of marble, a chisel, and a mallet and begin hammering I will realize I suck at it. But the thought of creating something from marble is just awesome and I just really want to try it.

while I know very little about sculpting with chisel you'll probably suck like anyone else who tries something for the first time. You'll probably need good spatial and visualization skills, great coordination as in percision and power, and a decent supply of money for new materials. Not to mention marble is heavy.
