I would like to offer a suggestion. These calendars that are monthly planners, or those that have enough space by the number/date, then you can see the view of month at a glance. You can make notations by each day. You could even have your own icon to put by the day when you don't have much to write.

You might begin to see how moods may be affected when approaching certain events. I believe you could learn simply by looking at your calendar as your "Game Book" and see what DB technique worked, or the 180 used. Then the next time, you know to have a different play during this game. (Sorry, I'm not very knowledgeable about sports terms, but hopefully you'll see what I'm getting at here.)

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
