Stoicism and Existentialism

I recently ran across a curious soul asking about what it meant to be Stoic.

Here was an answer he received:

"We create our own meaning and purpose."

No. Good God, no. And no again. That isn't Stoicism. We discover our own meaning and purpose. We hardly create it.

I respect a man who wishes to be an Existentialist, and I would never deny him his choice. But please, let's not confuse Stoicism and Existentialism.
