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.

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.

The professional dedicates himself to mastering technique not because he believes technique is a substitute for inspiration but because he wants to be in possession of the full arsenal of skills when inspiration does come. The professional is sly. He knows that by toiling beside the front door of technique, he leaves room for genius to enter by the back.
