On a daily basis, I like to write out a "To Do List," even including the mundane tasks I have to do at work each day. Things like "check the jail log" or "call the cops" or even larger tasks like finish my story that's running the next day. And as I accomplish a task, I get do cross it off and as I scribble it out, I feel good, like I've done something.
But it's not just day to day stuff I keep track of. I do it for other long-range stuff too.
