I'm not sure why you feel like you would lose a lot just because it's live, but either way, you should probably start at the lowest limit of whatever game you already play, so you can give yourself a chance to develop a feel for live play, and get comfortable with it, and then decide are you in the right game, or should you try moving up. There will be some things that will take some adjusting to, a lot of which were just covered in a thread entitled "Poker Etiquette". Check that out too. Good luck.
