Starting out, I bet I didn't get a lot of parts because of my strange voice. I'm not consciously thinking, 'Hey, sound like a squeaky dog toy mixed with a bagful of rusty nails.' It's just what my voice has done.
The point is the 'me' that you see before you is not the 'me' in my private little space, shape-shifting into the writing role, nor is it the 'me' that works with the actors. Here, at the end of the film doing interviews, I feel like I'm in disguise.
No one ever found wisdom without also being a fool. Writers, alas, have to be fools in public, while the rest of the human race can cover its tracks.
