One of the beauties of Omnifocus is that you can let your definition of, and list of, projects....evolve. The decisions you make today about what projects or contexts you want are by no means a permanent point-of-no-return choice.

You might consider by starting with a few big projects and then letting them evolve. Perhaps the notion of who "owns" the projects might help. I have one called personal, another called work, and a third called support, which isn't really billable work (I am a consultant) but which I need to do in order to work.
