I have two degrees in Communication and consider myself a good communicator as well as listener, but improv helped me to deepen those skills. I am a typical type-A personality who finds it hard to relax. Improv helped me learn to be present and being present helps you be better listener, because one of the fundamentals of improv is making your partner look good.
A lot of improv is terrible, even onstage with trained improvisers. But what makes it interesting, hilarious and endearing is the wholehearted attitude towards failure that good improvisers possess. Failure happens - it's imperative to learning. On the heels if the NYC-DOE test scores, we need to remember that more than ever.
