I try to define myself through my own choices rather than just accepting society's kind of you're that, you're that, let me put you in a box kind of thing.
I try not to limit myself. The actors that inspire me are the comedians and the people able to shape-shift into different roles and into different media. That ensures your longevity as an artist and prevents you from getting bored with yourself and, hopefully, prevents people from getting bored with you.
