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 need to start thinking less about the past and more about your future."
"Only you can decide what's best for you, Jesse."
"We can't change the world with only ideas in our minds. We need conviction in our hearts."
"I always get to where I'm going by walking away from where I've been."
"Continue your journey. Have faith in your cause."
"What if we are here for a reason? What if we are a part of something truly divine?"
"When you have a 'why' to fight, you can bear almost any 'how'."
"You can't understand where you're going if you don't understand where you've been."
"You've got to look at the bigger picture. Ask 'why' as well as 'who'."
"Having something to lose is what makes life worth living."
