What are the philosophical movie lines?

What makes me think deeply is the philosophical English "Yesterday is history". Tomorrow is a mystery. But today is a gift. That's why what I said to Po under the peach tree in the first part of Kung Fu Panda was called a "gift". Yesterday is history, tomorrow is still unknown. Only now, yes, now, grasping the present is a wise and practical gift. Po and Master Gui are both under the peach tree. I think it means that the world of peaches and plums is inherited by the wise. Why isn't this philosophy an interpretation of our lives?
