Thinking and spoken discourse are the same thing, except that what we call thinking is, precisely, the inward dialogue carried on by the mind with itself without spoken sound.
Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day. Asking for help isn't a sign of weakness, it's a sign of strength. It shows you have the courage to admit when you don't know something, and to learn something new.
I once heard a learned man say, "Every evil has its remedy, except folly. To reprimand an obstinate fool or to preach to a dolt is like writing upon the water. Christ healed the blind, the halt, the palsied, and the leprous. But the fool He could not cure."
Examinations, sir, are pure humbug from beginning to end. If a man is a gentleman, he knows quite enough, and if he is not a gentleman, whatever he knows is bad for him.

They help him to use the world for purposes of his own devising rather than understand and explain it.
He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
I do all the evil I can before I learn to shun it? Is it not enough to know the evil to shun it? If not, we should be sincere enough to admit that we love evil too well to give it up.
