When I was a kid, my brother and I made funny faces at each other. It must be genetic: my son does the same thing. I treasure photos of us together, like the four-in-a-row shots taken in old time booths. We mugged photos while he served in the Israeli Army. His funny faces reduced my anxiety. That’s the point: faces communicate stuff – faces make us feel stuff. I have noticed that leaders use this to motivate people and make strengths productive.
