Brené Brown, The Courage to be Vulnerable.

“But to separate that from the reality of vulnerability, I always ask a very simple question to people. I just say think of the last time you did something that you thought was really brave or the last time you saw someone do something really brave. You know, I think, without question — and I can tell you as a researcher, 11,000 pieces of data, I cannot find a single example of courage, moral courage, spiritual courage, leadership courage, relational courage, I cannot find a single example of courage in my research that was not born completely of vulnerability. And so I think we buy into some mythology about vulnerability being weakness and being gullibility and being frailty because it gives us permission not to do it.”
