Fnord says wise stuff. Being aggressive is going to make some very interesting things happen to you. For one, people will call your bets with some trashy draws, and you'll get sucked out upon more often because of it - because they don't want to get bullied off the pot by you. For another, some people are going to go out of their way to trap you, like our friend Marsman did. I do this all the time when I find the real enthusiastic aggro players in 6max games. Lots of checking, lots of folding, and then when a monster comes along they gleefully string themselves up in front of me. You have to be very careful about that.
