Ask yourself every couple of minutes, 'Can I go harder? Can I do more?' You've got so much power. Show me.

Treat yourself like a fat person with aches and pains and a suitcase full of excuses, and good luck-you'll stay exactly where you are. Train like an athlete and, though you may not look like one now, you will become one.

From this day forward, speak to yourself in a way that you would someone you care about.

Only exercise on the days you want to improve your mood.

Invest your time with people who will push you to be your best. Winners love to see other people win.

The vital difference between dreamers and achievers boils down to some very basic, simple habits. People with clear, 'written-out' goals who consistently honor their defined priorities tend to get results faster than others, and enjoy a greater level of happiness and long-term success in all areas of life.

Commitment is a muscle. The more you use it, the stronger it gets.
