Courtesy is doing that which nothing under the sun makes you do but human kindness. Courtesy springs from the heart; if the mind prompts the action, there is a reason; if there be a reason, it is not courtesy, for courtesy has no reason. Courtesy is good will, and good will is prompted by the heart full of love to be kind. Only the generous man is truly courteous. He gives freely without a thought of receiving anything in return.

Call the roll in your memory of conspicuously successful [business] giants and, if you know anything about their careers, you will be struck by the fact that almost every one of them encountered inordinate difficulties sufficient to crush all but the gamest of spirits. Edison went hungry many times before he became famous.

Jealousy... is a mental cancer.

J.P. Morgan, then past 70, was asked by the son of an eminent father why he [Morgan] didn't retire. When did your father retire? asked Mr. Morgan, without looking up from his desk. In 1902. When did he die? Oh, at the end of 1904. Huh! snapped Mr. Morgan, If he had kept on working he would have been alive still. Work is God's best medicine. It is God's medicine for man.

Many of the most successful men I have known have never grown up. Youthfulness of spirit is the twin brother of optimism... Resist growing up!

The fittest, not the richest, make the most enviable mark. Pampered sons of plutocrats may shine for a time in society, but not in the world of affairs and of service unless they rip off their coats and get to work early and stay late. To be born with a golden spoon in the mouth is more of a handicap than a help in attaining worthwhile success in this age.

We must learn that to enjoy happiness we must conscientiously and continuously seek to spread happiness. Selfishness is suicidal to happiness.
