Growing up on a farm, I saw that if I didn't go to the military or go to school, and I knew my mom and my family wasn't going to be able to send me to school out of their pocket, so it basically came down to athletics. I knew I didn't want to work on a farm. I knew I didn't want to do manual labor the rest of my life.

I've said numerous times the hardest job in America isn't being a professional athlete. It's not being a matador or having some job that puts your life at risk. The hardest job in America is being black, because it's the one thing you can't outrun.

Colin Kaepernick had a... maybe he had an epiphany. Maybe he had a realization that 'I have a higher calling the playing quarterback for the San Francisco 49ers.'

When I went to the Pro Bowl, I went as a tight end. When I made the All Pro team, I made it as a tight end. When they introduced us and I ran out of the tunnel, they introduced me as a tight end.

All too often, technology is treated as a silver bullet for perceived problems in education. This sometimes leads to knee-jerk investments, using scarce resources to invest in software or hardware without a clear notion of how either might actually empower learning.

Knowledge is exploding, so you need to commit yourself to a plan for lifelong learning.

Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing.

We do not need an immigration policy that displaces American workers or American students and drives up costs in education.
