Recently I started using specific colors of ink for planning ahead vs recording what I actually did. I write all my plans ahead of time in black pen. Then on the day, the only pen I have in my hand is blue. I check off what I accomplished, and write in emergent tasks (items that weren't planned but come up during the day). It's very interesting at the end of the day to see what I originally intended to do that day (black) and what I ended up actually doing (blue).
Have you done a similar experiment? If you're having trouble getting certain tasks done and aren't sure what you spent your day doing, this is a very valuable exercise. It creates an easy visual of intentions vs actions.
