The Meaning of Life is the Spontaneous Joy of Existence.
To exist is joyful. It is an inherent thing, underlying all else. It is the foundation that all is built upon, and why those who have no cares are full of joy.
It is where laughter comes from. Exposure to the spontaneous. And why laughter both cannot be faked and is contagious, because it is the universal language of the soul.
All of our pain and frustrations are byproducts of our attempts at avoiding the spontaneous, of plotting out and trying to game a reality that isn't meant to be gamed.
Follow that thread of thought to its conclusion, to wherever it leads you. Every individual path, no matter how similar, is still unique.
Life gives life.
