Having an experience is what earns the profundity of what otherwise would be a trite statement.

"The path is made by walking."

"The meaning of life is the friends you made along the way."

The ur-insight below most of them: "It's not the destination, it's the journey."

Hallmark Card style statements… that are deeply profound once you have the experience that activates them.

When you sum it up to something too short it only makes sense if you were in the same mental state and the same environment.
