It's good to have an interim time period. I usually set my rolling To Do list weekly. Early every Monday morning (like today) I figure out what I need to get done, and it gives me a chance to look at the bigger picture. Some people do this monthly, but I find weekly works better.

I use Evernote to keep track of list, but that's not based on any tremendous amount of research. Someone else told me that's what they use, and it's easier for me to find things there than on paper.
