I have always been a "make a list" person; jot it down, don't forget. I have been a big fan of "sticky notes" because I can write reminders and put them wherever I want. If I write all my notes on little note pad sheets, I end up with a stack of little note sheets.
The only problem with a bunch of little note sheets is: sometimes one will get misplaced or lost, then I forget what I wanted to remember. Maybe I should use a small notebook in the future, as long as I don't forget where I put it!
