This is was my whiteboard in 2008 for March to-do. I was going through some old folders (yes I'm at work on Sunday) and stumbled across all these old to-do lists.
As an interesting overview as to how my brain works, I can still describe each of these items in detail, why they were on my to-do list, the overall importance of them, and their resolution (same for the tasks assigned to my reports on the board).
On the other hand, I cannot remember anything about them from a time perspective - when I started working on them, when I finished them, how much time they took, etc. In fact a fair portion of that does not seem like it was something I worked on a year ago - it seems older or newer.
Apparently time does not function properly in my brain.
