You first need to identify why you've experienced burnout. In some situations, this will be obvious. Other times, it will take time and introspection to uncover this.
First, look at any resentment that you feel towards your work. Often, feelings of resentment point to something important that is missing.
Here's a good example: Jennifer manages a team halfway around the world, so her workday often starts at 6 a.m. She doesn't mind this because she likes her team and her job. But she feels resentful when her boss forgets that she works so early and repeatedly asks her to stay late, which causes her to miss important time with her family.
In this example, burnout didn't occur because Jennifer disliked her job; in fact, she loved what she did. She experienced burnout because she hated missing out on family time in the evenings.
Take time to think about any negative feelings that you have about your role, and, perhaps, use a technique like the 5 Whys to get to the root of the problem. Once you've identified the cause of your burnout, write down at least one way that you can manage or eliminate that source of stress or unhappiness.
Another useful method for identifying underlying causes of burnout is to keep a stress diary . Each day, write down what causes you stress and record why the event stressed you. Stress diaries can be illuminating, so long as you keep up with them for a reasonable period of time.
Once you discover the root causes of your burnout, look at what you can do to resolve it. This might involve delegating some of your responsibilities to others, adding more autonomy to your job, working from home one day a week, or even changing roles.
