Managing your workload with a to-do list can be a productive way to organize your work and keep yourself on task. But don't let your list become a collection of everything you want to do but will never have time for. Make sure each item on your list has a time and place attached. Don't add "write management presentation" without including the day and time slot in which you'll do it.
Consider foregoing the list and scheduling items on your calendar instead. You may still want a place to write down things you hope to get to, but be sure that each day you know what you need to accomplish and when.
