Record every important thought, when it hits you, so you forget nothing. Track everything that is time- or date-sensitive on your calendar. Break your to-do lists down by when and where you can do those things. Single out the items that will take more than one step to finish and track them separately. Clearly distinguish between things you are actively committed to completing and the things you’ll get to, but can’t focus on now. Keep good reference systems. And, review often.
