I think of myself as unconventional, I guess. I maybe always had a problem with authority, like a stubbornness about what's expected - despite wanting to get some recognition through performing - but also not always wanting to do the expected thing.
I am basically a shy person, so performing sometimes helps me focus - having all those people concentrate their attention on you. I don't see it so much as becoming another person onstage; it's more exploring a different side of your personality.
For me performing has a lot to do with being fearless.
