It is important to learn the art of prioritizing.
To Prioritize is simply the ability to determine the most important tasks and arranging them in order of importance.
Creating lists is a helpful way of capturing tasks, and then, learning to arrange the tasks in order of importance (see chart below). Otherwise, you may find yourself multitasking and jumping from one task to the other, when your list is not in any particular order; which could be stressful. While the ability to multitask is a great skill, it comes with its drawbacks.
Knock things out of your list progressively; this helps you get organized and ultimately manage your time better for stress-free living.
