A great philosophical thinker, writer and teacher, Aristotle believed that the universe is in a state of constant motion, always changing, always evolving. However, at the same time, there is one thing that remains a constant in everything—what he called entelechy or one's essential potential.
Aristotle believed that everything on this planet possesses its own entelechy, or as he coined it, "having one's end within." Entelechy is a vital force that motivates and guides an organism toward self-fulfillment.
Consider the mighty oak tree. Its journey to greatness begins with a small acorn seed. Of course, the seed has to go through certain changes and stages of development in order to reach its full potential, but the potential is a constant: to become an oak tree. You will never see an acorn become a petunia plant, an umbrella or a pizza.
According to Aristotle, there is always a reason for everything that happens. Your experiences are designed to shape you, define you and, hopefully, grow you into the mightiest you possible.
