The pro in whatever field he happens to work, the real pro! doesn't follow standards, he sets them. And the first step toward becoming a pro in anything that you want very much to do is to learn the rules. The armature is the person who doesn't know the rules and what's even worse is that he doesn't know that he doesn't know the rules.. The armature when he fails at what he does, he says, "well, that's how the cookie crumbles. "He finds ways of finding exterior reasons for his failures. We tend to look inside of ourselves to explain our successes but outside of ourselves to explain our failures. But the pro accepts responsibility for his acts.
There's the story of a football coach whose team had won four games in a row. When asked by reporters for his secret, the coach went into detail telling of his superior methods of coaching, choosing men, scouting and so on. The following week, his team lost. When asked, "why?" he said, "it rained." And one reporter asked, "just on your team?" The real pro would have said, "they came a better team than we did today." But the armatures are always scrambling for excuses. He spends the time looking outside of himself for reasons for his failures that could easily be used to bring about success the next time if he decided to turn pro and take the time to learn the rules.
We tend to look inside of ourselves to explain our successes but outside of ourselves to explain our failures. (Earl Nightingale)
