I just wrote something about why I embrace vulnerability the other day. In it I quoted extensively from Brene Brown, who has been researching vulnerabily for the past 16 years. Essentially, she said that if you want to have deeper relationships or more meaning in your work/purpose, vulnerability is the path. She’s got a pretty cool TedTalk on it as well as some awesome books and I love her style because she very vulnerable tells on herself all the time in explaining her findings.
I too enjoy the writers you named for that exact reason.
