I talk often about being intrinsically motivated by learning. It's the primary driver of most of my activity.

When I struggled with a depressive episode in 2013, I realized that I had a glitch in my thinking about my own motivation. I had separated learning and teaching into different concepts.

In the mid-to-late 1990s, I was an entrepreneur-in-residence at the Kauffman Foundation working with Jana Matthews on 'learning programs for high growth entrepreneurs.'

What I'm looking for in my interaction is critical thinking on the part of the person pitching to me.

I am shocked and deeply saddened by McQueen's death. He was a genius, and his talent was second to none. Like many others, I always cited him as a hugely inspirational leader of world fashion. He will be greatly missed.

Leadership is something you earn, something you're chosen for. You can't come in yelling, 'I'm your leader!' If it happens, it's because the other guys respect you.

Leaders are for calling people to their better angels, for helping guide them to a kind of sterner, more mature sense of what we need to do. To me, Reagan's brand of leadership was what I call 'a liturgy of absolution.' He absolved Americans almost in a priestly role to contend with sin. Who wouldn't want that?

Former President Shimon Peres was a leader and a statesman, and an especially wonderful friend to all of us. He will be missed dearly.
