SEAL training was a great equalizer. Nothing mattered but your will to succeed. Not your color, not your ethnic background, not your education and not your social status.

To me, basic SEAL training was a lifetime of challenges crammed into six months.

My wife and I make the bed every morning, but it's a queen size bed today, as opposed to a rack, you know, a small single bed, which I had in basic SEAL training.

Basic SEAL training is six months of long, torturous runs in the soft sand, midnight swims in the cold water off San Diego, obstacles courses, unending calisthenics, days without sleep and always being cold, wet and miserable.

You can't change the world alone - you will need some help - and to truly get from your starting point to your destination takes friends, colleagues, the good will of strangers and a strong coxswain to guide them.

If you want to change the world, start off by making your bed.
