He Who Is Really Good Can Never

At Fifteen, My Mind Was Bent On Learning. At Thirty, I Stood Firm. At Forty, I Had No Doubts. At Fifty, I Knew The Decrees Of Heaven. At Sixty, My Ear Was Receptive To Truth. At Seventy, I Could Follow My Heart's Desires Without Sin.

True Knowledge Is When One Knows The Limitations Of One's Knowledge.

A Man Who Lacks Reliability Is Utterly Useless.

If You Try To Do Too Much, You Will Not Achieve Anything.

To Know It Is Not As Good As To Love It, And To Love It Is Not As Good As To Take Delight In It.
