I think it's helpful to do something on a project every day, no matter how minor. If I'm feeling unmotivated that could be as simple as renaming some files I've been meaning to rename, or fixing the simplest of warnings in my project. Usually by the time I've done that, I'm in the project and rolling into the next thing. Conversely, it's important to take a day or two off after more vigorous stretches of productivity.
