Hard-headed optimist! Relentlessly peaceful and world-embracing!
Rigorous, unstoppable and notoriously sweet. He also said the best thing I've ever heard about conversation. (I must paraphrase).

Uplift from the downdraft - scaling the behemoth with leverage, too.
Check this one out. Best show yet, no kidding.
