I tend to jot down moments, lines, interactions that don't really make any sense. I try and explain these scattered notes to my close friends, and they become more and more logical. I see screenwriting as a bit like a math equation which I have to solve.
And trust, yes, which is important, but that is what I aim towards. Now that is difficult for some people, and with that desire to get things as good as possible, I would say that I'm probably regarded as quite prickly to work with.
