I use Work Rave to make sure I take breaks every so often. Otherwise, an entire day can go by with my eyes glued to the screen.

I use the Countdown Clock extension for Firefox to basically do timeboxing or other things that require a timer.

I have also started a simple text file listing my accomplishments. It's motivating to look back and see what I've done. Otherwise, I would just have todo lists with a bunch of things crossed off that don't tell me specifically what I've accomplished.
