Life is too short for mean anxieties.

The men whom I have seen succeed best in life always have been cheerful and hopeful men; who went about their business with a smile on their faces; and took the changes and chances of this mortal life like men; facing rough and smooth alike as it came.

A garden, sir, wherein all rainbows and flowers were heaped together.

A blessed thing it is to have a friend; one human soul whom we can trust utterly; who knows the best and worst of us, and who loves us in spite of all our faults; who will speak the honest truth to us, while the world flatters us to our face, and laughs at us behind our back; who will give us counsel and reproof in a day of prosperity and self-conceit; but who, again, will comfort and encourage us in days of difficulty and sorrow, when the world leaves us alone to fight our own battle as we can.

For to be discontented with the divine discontent, and to be ashamed with the noble shame, is the very germ and first upgrowth of all virtue.

The world goes up and the world goes down, the sunshine follows the rain; and yesterday's sneer and yesterday's frown can never come over again.

For science is ... like virtue, its own exceeding great reward.
