Every person on the planet has the capacity to contribute something unique to the world.
We each experience life from a perspective that has never been experienced before, and will never be experienced again... so each of us will see things and experience things no one else ever will.
There may be similarities, sure. But on a profound level, we are each fundamentally special.
What I call our "Contribution" is anything we contribute to the human race that comes directly out of our own one-of-a-kind experience. When you find it, your life's purpose is to share it — to "Contribute" it — with the world.
