I'll pile onto that. I love improv. It gave me a new set of mental skills that are difficult to train for elsewhere. It teaches you how to walk in a room and make the best of any situation and overcome that feeling of meeting strangers. I find any difficult work situation I can now approach from a "what can we do with this?" mentality, where I used to always dread rolling up my sleeves to do more work. Highly recommended to anyone, but especially anyone in a leadership role.
