Concentration and mental toughness are the margins of victory.

Success is a result of consistent practice of winning skills and actions. There is nothing miraculous about the process. There is no luck involved.

If a guy pays you five dollars, you give him seven dollars worth of work.

Friendship is a full-time job.

To me, the most important part of winning is joy. You can win without joy, but winning that’s joyless is like eating in a four-star restaurant when you’re not hungry. Joy is a current of energy in your body, like chlorophyll or sunlight, that fills you up and makes you naturally want to do your best.

We overreached our decision power. Sometimes our decisions have to fit the reality of the outside world.

My father once told me that anyone who worked for three dollars an hour owed it to himself to put in four dollars' worth of work.
