You feel a sense of purpose when you pursue things that matter to you. Through these experiences, you develop a better sense of who you really are and who you might become. We each need a meaningful project in every phase of our life.
Here is what the movies have to say about purpose.
"You cannot really live unless there is something for which you would die."
"It's kind of beautiful, isn't it, that we get to feel passion in this world."
"Frontiers are where you find them."
"Too many of us now tend to worship self-indulgence and consumption."
"Find something you care about and care deeply."
"I would be mighty grateful if you would make my purpose more clear to me."
"Sometimes we do the wrong things for the right reasons."
"What do you want, Rocco? What we all want – to not die young, poor or alone."
"Think only of what follows."
