If you can get out there and say I'm going to...I'm willing to fail at what I feel is right, that's it.
I wanted to find my limitations so I decided to do Shylock. And if I fail? I've never been afraid of that. I have other fears - doing bad work knowingly is the worst fear.
A "take" is an opportunity to fail ... and we think that we have to get it right all the time.
