I tell you, the difference for me is between being victimized, terrorized, numbed by reading about different disasters, or reducing the anxiety by getting up and doing something about it, at whatever level.
That's a tough question; I've been acting since I was 10. My dad was an entrepreneur, so I guess something along those lines. I wouldn't want a 9-5 job.
I think that obstacles lead to growth and ultimately, the most learning I've done in my life is between jobs.
