What Works for me is Keeping a Journal!
Do you keep a journal of your everyday activities?
Do you right a todo list?
I do it all the time. It sounds rudimentary and I know it. But it usually works.
Keep an index card of all your todo list and check them off as you accomplish them one by one.
It will keep you very organized and most of all you get to remember all the things you have to do other than all the meetings you have to attend.
