Yes, vocation not vacation! I think for most of us it's pretty clear that we have some kind of purpose in life. If life is just chance and our existence meaningless, then there is no real objective truth, feelings don't matter, life is not sacred, people have no real dignity, we are all just blobs of cells. However, as Christians we see life as a gift from God—the Creator of all things, pure being Himself. And this changes everything. He created us with a plan in mind for us to do great things. He made us for Heaven—to become saints—and calls us each into deeper union with Him so that with His help we can live up to our potential, becoming the best-version-of-ourselves.
