And make sure that when you go to these gyms and stuff, you talk to people. I met some guy today, a year older than I, very socially inept - first Brazilian Jiu Jitsu class he ever took. It seemed to be a good experience for him, although I beat the crap out of him in a sparring drill and ended his experience about 25 minutes early (I got sick of his whining, so I just went all out on him - if it hurts never whine - any fighter will have no problem pounding the whiny guy). And talk to people. He tried talking to me after and it got weird because he spoke so quietly, didn't look me in the eye, seemed nervous, and interrogated me - "So, where are you from? Yeah. Where o you live? Yeah." etc without even really listening to me or my replies. Kinda non-genuine. So when you go, just be social an not nervous. No one will judge you, seriously. Anyone who wants to be a fighter will find solace among the veterans, who ALWAYS want to help the new guys.
