I recommend starting small also. You have a 50% chance the market will move against you and if the stakes are high it is easy to panic and make mistakes when real money is on the line. I started off paper trading and did well, but when I started using real money, I jumped in to fast and made mistakes I didn't do on paper. I relate it to playing basketball. When I'm practicing, I can make most of my shots, but in a real game I miss most of them.
Good luck
