Can you step in the same river twice?

Life by the very means of existence is inconsistent. Each day is a new set of situations or a new place. You are not the same person you were yesterday. Or are you? Do you change? The very chemical make up of your body changes. But the essence of you stays the same. Or does it? It is confusing but entertaining. Maybe that is why life is interesting. Although, you need to be aware of these inconsistencies or changes and then appreciate them. Trust in the fact that doing the same old thing every day would be boring with our appreciation of subtleties.
