For myself the idea of "the most important aspect of life" is a temporal concept. It is a state of chaos and evolution simultaneously. Sometimes the most important aspect of life is just survival. Then it becomes routines and pleasure. I think it's really cool to even take a moment to ask the question literally. What is the most important aspect of life? For the past year or so (temporal) I have begun to find real happiness in life. After dissolving a toxic marriage I have had the freedom to pursue challenges and adventures that push me that much more to want to know the answer to the question in the first place.
Thanks slcraiders for the contest and the question.
