When human beings live together, conflict is inevitable. War is not.

So long as nuclear weapons continue to exist, so will the temptation to threaten others with overwhelming military force.

A healthy vision of the future is not possible without an accurate knowledge of the past.

We are not merely passive pawns of historical forces; nor are we victims of the past. We can shape and direct history.

The two things I'm most excited about are self-driving cars and speech. Speech doesn't sound like that much, but it's one of those technologies with the potential to change everything. Steve Jobs didn't invent the touch screen. He just made it work very well, and that's changed everything.

I don't want to sound too Oprah-ish or anything like that, but I really believe that if you have the power to imagine particular things, you have the ability to transform them.

The Dallas model, prominent in the South and Southwest, sees a growing population as a sign of urban health. Cities liberally permit housing construction to accommodate new residents. The Los Angeles model, common on the West Coast and in the Northeast Corridor, discourages growth by limiting new housing.

The message of transformation and how we all can live from our heart, not just from our head, was a very important message for me to learn in my own life.
