One way I stay organized is by a making a list every morning of all the things I need to get accomplished. I leave the list on the counter and I keep adding to the list as the morning and day goes on. As I accomplish each item on my list I cross it out.
If you really want to remember something important WRITE IT DOWN! We are all so busy especially with the holidays around the corner and the simple task of making lists and completing them will give you a sense of accomplishment.
