I'm pretty good with production, but I got the idea a while ago of picking up a simple dry erase board. It was just a couple of bucks, and on it I made columns, categories that corresponded to the different things I wanted to be sure to produce in a day. It helps me to look at it, because I can easily see what I haven't done and what I need to do. I put a check in each column when I do what I need to do for the day.
It's also really reassuring to look at later and see that I have actually accomplished a lot. It's handy for fighting that self-doubt and criticism that insists that I don't accomplish anything. I know better, but it's nice to see it in that very easy-to-understand, clear form on the dry erase board.
Usually my approach is, early on in my day, I think about what to do and put it into three categories: what I have to get done, what would be nice if I got done, and what I'd be thrilled to get done but don't expect to do. I'll be satisfied if I accomplish what I have to do, but it'll make me a little happier if I do more -- the things it would be nice if I could do. What I would be thrilled to do is usually too much for me to expect to accomplish in a day, but if I get it done, then that's super. But I don't expect it, and I'm not disappointed if I can't do it.
For example, in a day, let's say I need to produce at least one comic page. It would be nice if I could produce two comic pages...that's possible, and may even be likely. I'd be thrilled if I could produce five pages, but realistically that probably won't happen.
This way, at the end of the day, I can look back at what I've done and be satisfied, as well as setting a pace for my output, and I'm not too harsh on myself.
