Whenever you are feeling run down, take an honest look at how you have been thinking, feeling and acting. You will likely find a belief, behavior pattern or even a relationship that is out of alignment with who you really are. Perhaps you believe you have to be perfect at everything or you have been bending over backwards to get people to like you. Maybe you are dealing with mild depression or simply have too much on your plate right now. There may also be people or situations in your life which are draining your energy. Once you get clear on the root cause, you can weed it out and better direct your flow of energy in the future.
In time, you might notice that the reasons you feel run down have less to do with how much you are doing and more to do with the fact that in your heart, you would rather be doing something else entirely. From now on, try and listen to what your heart really wants. It may take meditation, or just a moment of silent tuning in to gain the clarity you need, but it is well worth the effort. When you know what you truly want to do, and honor that in all situations, you will find that getting run down is a thing of the past.
