I like guys who are confident but not cocky, who are comfortable with themselves, and who know what they want.
Most people would have given up when faced with all the criticism I've received over the years.
The quickest way to defuse fear or insecurity or anger is usually humor. I think comics figure that out quickly, and, once you figure it out, you think, 'Hey, if I can do this and get paid, that would be kind of cool.'
