Mark Twain said, "The two most important days of your life are the day you are born and the day you find out why."
I don't necessarily hold with the theory that each of us came here for one solitary purpose, and it's up to us to unlock the mystery of what that single purpose is. I do believe, however, that each one of us has a wide variety of gifts and a completely unique perspective and set of circumstances that can lead us to a particular path. I also think that we can change direction several times in our life and still stay true to ourselves and our passions.
It's important to be authentic—to be who you really are, not who someone else thinks you should be. And it's important to follow your passion, for when you combine your passion with the gifts you were given, you have an unbeatable combination!
Why are you here? What gifts are you in a unique position to offer the world? To offer those who love you and live with or near you? Those with whom you share a workplace? You are the only one on the entire planet with your personality, your particular experiences and your specific views on life. You are unique, truly a one-of-a-kind. So how you choose to spend your days and live your life can be unique to you, too. Just be sure it fits for you!
