Friendship is like a glass ornament, once it is broken it can rarely be put back together exactly the same way.

Do today's duty, fight to-day's temptation; and do not weaken and distract yourself by looking forward to things which you cannot see, and could not understand if you saw them.

You must not say that this cannot be, or that that is contrary to nature. You do not know what Nature is, or what she can do; and nobody knows; not even Sir Roderick Murchison, or Professor Huxley, or Mr. Darwin, or Professor Faraday, or Mr. Grove, or any other of the great men whom good boys are taught to respect. They are very wise men; and you must listen respectfully to all they say: but even if they should say, which I am sure they never would, 'That cannot exist. That is contrary to nature,' you must wait a little, and see; for perhaps even they may be wrong.

Feelings are like chemicals, the more you analyze them the worse they smell.

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.

Those clouds are angels' robes.

Have charity; have patience; have mercy. Never bring a human being, however silly, ignorant, or weak--above all, any little child--to shame and confusion of face. Never by petulance, by suspicion, by ridicule, even by selfish and silly haste--never, above all, by indulging in the devilish pleasure of a sneer--crush what is finest and rouse up what is coarsest in the heart of any fellow-creature.
