When you hit your strive, and you feel confident in what you're doing and in your process, you really want to do more and try lots of different things. I've also really worked on my breathing, which is a funny thing to talk about, if you're not an actor. I think breathing is actually the key to a lot of opening up of other parts of yourself that you haven't used, for any job, but particularly in acting.
