Success is never final. In dialogue, people become observers of their own thinking. It's not what you don't know that hurts you, it's what you know that just ain't so. Don't find fault. Find a remedy.
Honest differences are often a healthy sign of progress.
Excellence is to do a common thing in an uncommon way. I'm a great believer in luck, and I find the harder I work the more I have of it. But I cannot tell you what it is in a way that you can now understand. You must be willing therefore, to undergo certain experiences as I direct you to undergo them, so that you can learn what it is that you need to know and what I mean by the words I use. Then and only then can you make an informed choice about whether you wish to learn this new competence.
