Passion can power a purpose driven life. A given field or endeavor can draw us into its orbit. When this happens, we might feel as if we do not need to expend energy pursuing whatever it is that has captivated our interest. On the contrary, it often turns out that something we have a natural affinity for provides us with more energy than we put out in its pursuit. How do we know if we have passion for something, be it art, music, sports, an entrepreneurial endeavor, etc.? One signpost of our predilection might be that we are always thinking about that activity. When we wake up in the morning it is on our mind. We think about it when we go to sleep. Oh, and during the day when we are supposed to be doing others things, this activity exerts a continual pull on our attention.
