I worked with a friend for a while and he used a to-do list, like the one you use, it just itemized what he had to do for the day. He got a big smile every time he checked an item, so i guess it was great for him. I never got the habit, I am not very organized and rely on my memory. As you can imagine, some days its not that i didn't get to finalize a to-do list, it is just that I do not have one and forgot a few things I had to do. In summary I think a to do list is great, just that I don't like them.
