The best system I came up with:<p>1. Get a small spiral-bound notebook, say 3x5 or whatever is sitting in the supply cabinet.<p>2. Write today's date on the top of the first page. Write each task on <i>one line</i> on the page. (You only need enough detail to remember what the task is.)<p>3. As you complete tasks, draw a line through them. It's more satisfying that check marks or whatever.<p>4. As you add tasks, just write them on the today page.<p>5. Or, if you know you aren't going to get to them until tomorrow, write tomorrow's date at the top of the next page and put them down there.<p>6. Or, if you know you can't get to it until Monday, write the dates on the pages in between, one page per day, until you get to Monday and write it there.<p>7. At the end of the day, look at the list of tasks you didn't get to. Carry them over to tomorrow's page and mark them out on today's. It feels great.<p>8. Try not to carry too many over to any particular day; after two or three, put the rest on the next day's page. Some days I'm only good for one or two things.<p>It's all about a) making sure you remember things, and b) making sure you aren't overwhelmed by what you have to do at any one time. (I almost never move a task <i>up.</i>)
