Now Habit + Pomodoro + GTD
I thought I would also add, I've found Pomodoro to mesh really nicely with Neil Fiore's THE NOW HABIT methods as well. It is the very essence of "consistent starting," and since a pomorodo with break is 30 minutes, it works very nicely in Fiore's unschedule.
I use GTD methodology to define my work, and pomodoro to accomplish the work I've defined. I've found it to be an almost seamless combination.
Collect. Process. Organize. Review. Do. That really is all there is to it.
