I remember reading a theory that life itself springs from entropy. Energy finds way to expend more energy. And yes, it's important to remember our mortality, as individuals and as a species. In fact, I'm increasingly realizing much of what humans do -- and much of what individuals are fundamentally anxious about -- comes down to mortality. Why do we build careers? Civilizations? To create something that lasts beyond us. But facing that directly leads you to make more rational choices and perhaps find more peace. Knowing that life is temporary, what do you do? How do you make best use of your time on this planet?
