“A man of over thirty might be held to be at the height of his powers, but not necessarily of his wisdom.”

“A truly humble man is sensible of his natural distance from God; of his dependence on Him; of the insufficiency of his own power and wisdom; and that it is by God's power that he is upheld and provided for, and that he needs God's wisdom to lead and guide him, and His might to enable him to do what he ought to do for Him.”

“The more tranquil a man becomes, the greater is his success, his influence, his power for good. Calmness of mind is one of the beautiful jewels of wisdom.”

“The eyes might be the windows to the soul, but a man's hips were his seat of power.”

“Rather I think that a man who ... is willing ... to value learning as long as he lives, not supposing that old age brings him wisdom of itself, will necessarily pay more attention to the rest of his life.”

“You will never have a greater or lesser dominion than that over yourself...the height of a man's success is gauged by his self-mastery; the depth of his failure by his self-abandonment. ...And this law is the expression of eternal justice. He who cannot establish dominion over himself will have no dominion over others.”
