Peace must be found in the imperfect present

— The Stoic Emperor 

And here is the longer version of it:

"I will be happy when I reach a state free of misfortune."

Unlikely. The perfected future never arrives. 

Misfortune can be minimized, but never eliminated.

Life is full of seemingly endless trouble, and then life ends.

Find peace in the imperfect present.

— Marcus Aurelius
