For each year, I make a MindManager map that looks like this:

I'm only showing the top levels of each branch (which MindManager will do automatically) to protect my privacy, and because you'll fill it with your own stuff anyway. I have hyperlinks for each month that will pull up the MindManager map for that month. Here's an example:

Finally, each week is also hyperlinked to its own map, so I can track at a weekly level:

I use the daily items for two purposes. One is that it shows me my meetings and deadlines. But the other is that I am using it to get a better handle on how long it actually takes me to get things done, so that I allow for that in my future planning. It also helps me to concretely answer the question "where did the time go".
There is also a natural tendency to do an end-of-week and beginning-of-week review as I open or set up the Map for that week, also at the end of the month, and at year end.
I also have project-specific mindmaps that show me things like research design, links to research tools, track collaborators and conference presentations and publications that are tied to a particular project. I sometimes use it to display hierarchical representations of complex analyses so I can see patterns at multiple levels.
I get no kickbacks for this, I just like the software. A lot.
