It's kind of sad and depressing at first, but once you realize that there is no purpose it opens you up to create your own. One of my favorite episodes of Rick & Morty when Rick makes that butter server robot with AI. It asks "What is my purpose"? Rick replies "To pass the butter". The robot is visually upset and depressed. You see if you knew your purpose you would be sad about it. Life would be easy. It wouldn't allow for all the wonderful things that happen in life.
Let's not live life like tomorrow doesn't exist. Let's live life like there is no purpose and what we are meant to accomplish is up to us. Use your inner compass to tell you where to go and what to do. It's silly that this is so difficult to do. We rely on others guidance far too much. So, stop it. Find what makes you happy and do that until it doesn't and then find what makes you happy again.
I love you all and that is my purpose ;)
