Recently two videos have been recommended to me. Both (with the usual caveat that we read and watch material critically) are well worth watching and being challenged by.
The first was recommended by one of my daughters (an introvert) and she found this to be very affirming of her own character and traits. Teachers and pastors, I believe, will be challenged by this.
The second is also a TED video and speaks of vulnerability. Brene Brown speaks of her own journey. Christians, I believe have a chapter to add to this story about the one who made himself totally vulnerable for us, but even by itself, it is a powerful image of our humanity.
