In the last five years, what new belief, behaviour, or habit has most improved your life?

I gained a humility that I needed in order to balance my audacity. I wanted to find the smartest people who would disagree with me to try to understand their perspective or to have them stress test my perspective. I wanted to make an idea meritocracy. In other words, not an autocracy in which I would lead and others would follow and not a democracy in which everybody's points of view were equally valued, but I wanted to have an idea meritocracy in which the best ideas would win out.

Even I can't predict what kind of car we will be driving 20 years from now, but my time at Babson taught me to embrace change rather than run from it, and I urge all of you to do the same.
