"Now. This is important. We come to the meaning of the word amateur."
He brought his broad hand down flat and heavy on the table.
"If there is one thing that annoys me, it is the misuse of the word amateur as a synonym for beginner, for someone who is not well equipped or fully trained. The word doesn't mean that! Go to etymology. Go back to the origin of the word. What does it mean? It means one who loves, one who has a devotion to. An amateur athlete is one who loves sport."
He poked a finger down on the desk.
"All right. You say, can't a professional athlete love sport? Certainly. I'm sure that Babe Ruth was an amateur at heart. He would have played baseball if he had never made a dime from it. Certainly. He loved the game. I think Henry Ford was an amateur. I think Thomas Edison was an amateur. They loved what they were doing. They were amateurs."
He frowned and said, almost to himself, "Of course, under our rules they'd be considered professionals."
He waved his arm and went on.
"But you take most professional athletes. They keep themselves in excellent shape and they work at their jobs. Why? They have to!"
He paused for dramatic effect.
"Well, now. An amateur doesn't have to, but he does anyway. Why? Why should he punish himself and make the sacrifices every great athlete has to make? Because he loves to play. He wants to win and he plays to win because it's fun to win, but if he loses he congratulates the winner and tries harder the next time. And even when he loses he's gained something valuable from the experience. But the professional? The professional plays to win because he's got to win! He can't afford to lose. If he loses it hurts his income."
