You may not know it yet, GL, but you've already figured out the most important tricks: making pizza regularly, staying active on the boards, keeping your mind very open to people's suggestions, and trying new things. This is evident in the fact that you've been a member for at least two years but mostly haven't been active until lately (and because you've been very active lately).
Just like anything else, if you don't make pizza regularly, it's hard to keep learning and improving. I haven't made a pizza in a few months, so I know if I decided to start making it again right now I'd be a little rusty at first; I'd have to refamiliarize myself with at least a few parts of the process, even though I've done some of it thousands of times over the years. Interestingly, though, I think staying current with the boards keeps me from getting as rusty as I would if I just didn't think about pizza at all during my periods of inactivity. By keeping up with the boards, I kinda still make pizza regularly in my mind, even if I don't make it in my oven.
