Most of my writing (by word count) happens in what I call my "gonzo mode."

The feeling is "I will explode if I don't get this out of my head right this second."

Writing is a kind of self-soothing behavior I do to calm the pain of not writing an idea down.

Later, I can clean up whatever I wrote up in that mode into something a bit more presentable.

These explosions of writing happen in little bursts, when my schedule gives a small window for them to happen.
