When I first meet many of my clients they are overworked and starving for fun. While working hard is great, hard work without fun can make you very unhappy and can even lead you to behave in unhealthy ways.
The best way to avoid malnutrition in the fun department is to pay attention to and follow your bliss. If you are feeling overworked and stressed out, may I suggest that as soon as humanly possible you set aside some time to scan your life and look for ways you can add some pleasure back. Perhaps you can choose to listen to your favorite music while you’re on the train or you can sign up for a class about a subject that intrigues you. Adding more joy to your life will help you to feel refreshed and enable you to have more energy. You’ll also notice that the people around you will be more attracted to you and if you are single that isn’t a bad thing.
If you are going to be an overachiever, you might as well do it in the fun department.
