I got into acting because my teachers kept nudging me into it. The power a teacher has to influence someone is so great. I can't think of a profession I have more respect for.
I watched a couple of really bad directors work, and I saw how they completely botched it up and missed the visual opportunities of the scene when we had put things in front of them as opportunities. Set pieces, props and so on.
Neophyte writers tend to believe that there is something magical about ideas and that if they can just get a hold of a good one, then their futures are ensured.
