During the day you will probably encounter various new to-dos and deadlines that need to be scheduled. For example, a professor might announce the date of an upcoming exam, or a friend might give you the date and time for an upcoming study group. The key is to get these obligations out of your head as soon as possible so your mind is not unnecessarily cluttered. Jot down a quick reminder on your list, in the Things to Remember column, as soon as they occur.
