I think I'm a writer because I'm the ultimate loner.
I have a thought, an idea, and my first impulse is to not talk to someone about it, but to write it out, like I'm doing right now.
When I see it typed, it makes sense. I begin understanding it. Then I want to think about it again, alone, rereading the words.
And once I grasp it, I let it go. This thought is gone. I start thinking the next one.
