Something I like doing to get myself in a different mindset is that I tell myself I am not allowed to work on "good" ideas at home. I will literally only work on a personal project if it sounds "dumb" (eg: a Mobile Virtual Pet Rock). This lets me drop all of the development best practices that I normally use "at work" (TDD, Agile, CI, portability etc), and enter a mind-state of just messing around with some code. Sometimes a good idea comes out of it too.
