It's good to have a lot of once-in-a-lifetimes in your lifetime. If you get the chance to skydive, go skydiving. If you're offered a part in a weird Shakespeare play in San Diego, slap on some tights and rock out some iambic pentameter.
The way I write is that I'll actually have a conversation out loud with myself. In a weird way, I just kind of get schizophrenic and play two characters.
