The essence of professionalism is the focus upon the work and its demands, while we are doing it, to the exclusion of all else.

The professional conducts his business in the real world. Adversity, injustice, bad hops and rotten calls, even good breaks and lucky bounces all comprise the ground over which the campaign must be waged. The field is level, the professional understands, only in heaven.

Resistance cannot be seen, touched, heard, or smelled. But it can be felt.

Courage is inseparable from love and leads to what may arguably be the noblest of all warrior virtues: selflessness.

Don't cheat the world of your contribution. Give it what you've got.

Turning pro is a mindset. If we are struggling with fear, self-sabotage, procrastination, self-doubt, etc., the problem is, we’re thinking like amateurs. Amateurs don’t show up. Amateurs crap out. Amateurs let adversity defeat them. The pro thinks differently. He shows up, he does his work, he keeps on truckin’, no matter what.

If you were meant to cure cancer or write a symphony or crack cold fusion and you don't do it, you not only hurt yourself, even destroy yourself. You hurt your children. You hurt me. You hurt the planet.
