True, we should stop procrastinating. Humans have a weird relationship with time anyway. Not just when it comes to productivity, but also with how we view life in general. We either live in the past, reliving past hurts or longing for the "good old days", or hunker for the future, hoping that tomorrow, next week, next year, will bring us a better life. But as you say, all we have is now and we need to focus on the present.
