I find it so interesting that people remember things different ways.
Some people make lists. Let's divide that even further: some people make lists on paper and love to be able to cross them out or highlight them when the tasks are done. Tami's one of those.
Some people use a computer program. Amy puts all of her tasks into ACT. She sets alarms, she even puts in tasks that are done daily - i.e., three times a day she gets a message on her computer to Check Faxes.
Some people write notes. My husband, George, writes notes. He writes notes everywhere. The grocery list is on the kitchen counter, the note pad is on his "desk" on the patio. He also remembers things with piles - the envelopes spread out on a table, the folders spread out on the floor, the newspapers piled beside his chair.
Then there are people like me. I do all of the above. My "Things To Do" on the computer is so long I really don't see it anymore. Each evening I write out a "Things To Do" list on a piece of paper - that's the important things to do tomorrow. And yes, then there are the slips of paper, the sticky notes, the notes from a phone call while I'm in the grocery store that are written on the back or a receipt or deposit ticket.
It's easy if you're always in one place. Then you can organize your desk, your workplace. My problem is that I get "things to do" at all kinds of times, in all kinds of places. Sometimes I'm driving down the highway when I answer my iPhone and get "things to do". Yes, maybe I can call jott - but I can't remember phone numbers to put in jott. What about that promise you made to someone when you were at the cocktail party? The request from a fellow sailor out on the water? the request from someone on the treadmill next to you? Those are the problems.
How to YOU remember things?

Patricia - I'd heard St. Anthony could sell houses, but I didn't know he could find keys!
Lisa - that works. I sure hope you never lose the notebook.
Sharon,
You do all these things, you must be very organized. I used call logs aka to-do list for me. Personally I work best if I have everything in once place, that way I'm rarely looking for a phone #. I alternate the paper colors for my lists. That' also helps when I'm looking for something from a prior week (s).
Bill - can I take you along with me to remember everything for me?
Lynda - sometimes I think I was more organized when I used different colored Excel sheets and manual input - the problem there for me is going back and finding things.
Sally - you are SO organized.
