Brené Brown researches courage, vulnerability, shame, and empathy. The about page on her website says, in part:

The bottom line: I believe that you have to walk through vulnerability to get to courage, therefore . . . embrace the suck. I try to be grateful every day and my motto right now is “Courage over comfort.” I do NOT believe that cussing and praying are mutually exclusive. And, I absolutely believe that the passing lane is for passing only.
