Writer's Block: Where Did My Words Go?

I have a degree in writing, and I want to be a writer, but I excuse my way out of it all the time: I can't find the notes I'm looking for. My favorite pencil has gone missing. I don't have enough time to immerse myself in writing today. I should make sure I didn't miss anything on Facebook. I'm not going to be able to focus until I trim my nose hair. I've got a million of them. Today I'm just stuck. So I rewrite what somebody else has written--a technique that often works for me.
