You had a fear of scuba diving and your ability to do it that you got over and now look at you! Scuba diving all over the place! It wouldn't be an immediate thing, and you shouldn't pressure yourself. Truthfully, the idea of scuba diving scares the shit out of me, and while I've never driven to Brooklyn alone and it might make me nervous the first time or so, and weren't you pretty nervous on your first dives?
