Haven't reached the optimum yet, so using an online notes app, and a physical journal (cheap yearly planner, not using Moleskin yet) as well. I think I will stick with the later, and maybe an online version of the final draft.

The key is to spend a significant amount of time in writing and formatting it. Think tens of minutes in what is roughly a five day period. This really works for me.

By that, I mean I am always aware what I need to do.

By no means I am in a perfect shape. I slack off sometimes, I don't do anything and waste some time.
