Retired US Navy Four-Star Admiral William McRaven spoke to the students at the University of Texas about what needed to be done to change the world:

I have been a Navy SEAL for 36 years. But it all began when I left the University of Texas for Basic SEAL training in California. 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. It is six months of being constantly harassed by professionally trained warriors who seek to find the weak of mind and body and eliminate them from ever becoming a Navy SEAL.

Every morning in basic SEAL training, my instructors … would show up in my barracks room and the first thing they would inspect was your bed. If you did it right, the corners would be square, the covers pulled tight, the pillow centered just under the headboard and the extra blanket folded neatly at the foot of the rack — that’s Navy talk for bed.

It was a simple task — mundane at best. But every morning we were required to make our bed to perfection. It seemed a little ridiculous at the time, particularly in light of the fact that were aspiring to be real warriors, tough battle-hardened SEALs, but the wisdom of this simple act has been proven to me many times over.

If you make your bed every morning you will have accomplished the first task of the day. It will give you a small sense of pride, and it will encourage you to do another task and another and another. By the end of the day, that one task completed will have turned into many tasks completed. Making your bed will also reinforce the fact that little things in life matter. If you can’t do the little things right, you will never do the big things right.
