One of the best organizing and productivity practices is to make a weekly to-do list.  A to-do list clarifies your priorities, making it easier for you to focus on what needs to be done, which in turn improves your productivity. Experts recommend creating a weekly to-do list on Sunday to help you map out the week ahead.

Even with a list in hand, you may be inundated with new and/or required items to deal with that could derail you from your priorities. Tory Johnson writes that you should organize your to-do list into four categories, using a triage method. These are:

1. Do immediately: Use this category for urgent and important matters that require your attention now.

2. Delegate: Some items on your list can be handled by somebody else.

3. Drop: Does this item further your overall priorities? If not, remove from your list.

4. Defer: If an item is important but not urgent, you can postpone it to a more convenient time.
