First off, a pro is necessarily getting paid to do what he does, and that’s a tough trick these days all on its own. But a pro is also defined by the scope and practice of his operation. A pro has sources. A pro knows how to spot a lie. A pro does the work. A pro gets it right. A pro knows how to hustle the corner, but he also knows his way around a paragraph. A pro does it all, and he does it all well, without vanity or fireworks. A pro doesn’t leave any holes or openings, in his soul most of all.
