Yes. Sit down and imagine how you're going to feel when you are finished. Really try to make yourself believe that you're done. If these are features, imagine using the product with those features in place, and how much it adds to it. If it's design, think about how much better it's going to look when your through with it. If it's performance, think of how your product is now more capable of handling more requests or is faster and lighter-weight feeling. Whatever it is on the todo list, I'm sure there's a good reason it's there.

Now that you've imagined how much these things on your todo list are going to improve whatever it is you're working on, and how awesome it's going to be when those things are in place, why not get to work?
