Am I being typecast as a horrible person? I don't know. I don't think so. But if it happens, I'd rather get to play that, because there's nothing fun about being sweet. Sweet can be so boring, so I'd be happy staying away from that.
I think it's imperative to follow your heart and choose a profession you're passionate about, and if you haven't found that 'spark' yet, if you're not sure what you want to do with your lives - be persistent until you do.
