How do significant life events or the passage of time influence your perspective on life?

My theory is that time is a circle. Each minute we live collects behind us and pushes us forward to our inevitable end. This might be why we experience deja vu. Or even why time seems to pass faster the older we get. Also, perhaps why we should be, not only, paying attention to history, but really learning the lessons it has to teach us, so we won’t be doomed to repeat the mistakes we made in the past. Politics is the pendulum of the circular clock that is time itself. Swinging both left and right, never pausing where we should be, in the middle.
