“I had troubles of my own, and even the most heartening of philosophical vistas is no match for, say, a toothache, if it happens to be your own.”

Context: I am delighted to see how many young boys and girls have come forward to obtain honourable marks of recognition on this occasion, — if any effectual good is to be done to them, it must be done by teaching and encouraging them and helping them to help themselves. All the people who pretend to take your own concerns out of your own hands and to do everything for you, I won't say they are imposters; I won't even say they are quacks; but I do say they are mistaken people. The only sound, healthy description of countenancing and assisting these institutions is that which teaches independence and self-exertion... When I say you should help yourselves — and I would encourage every man in every rank of life to rely upon self-help more than on assistance to be got from his neigbours — there is One who helps us all, and without whose help every effort of ours is in vain; and there is nothing that should tend more, and there is nothing that should tend more to make us see the beneficence of God Almighty than to see the beauty as well as the usefulness of these flowers, these plants, and these fruits which He causes the earth to bring forth for our comfort and advantage.

Context: Roadstrum had always believed that he had troubles enough of his own. He seldom borrowed trouble, and never on usurious terms. He knew that it was a solid thing that sheep do not gather in taverns and drink beer, not even potato beer; that they do not sing, not even badly; that they do not tell stories. But a stranger can easily make trouble for himself on a strange world by challenging local customs.
"But I am the greet Roadstrum," he said, suddenly and loudly. "I am a great one for winning justice for the lowly, and I do not scare easily. I threw the great Atlas at the wrestle, and who else can say as much? I suffer from the heroic sickness every third day about nightfall, and I am not sure whether this is the third day or not. I say you are men and not sheep. I say: Arise and be men indeed!"
"It has been tried before," said Roadstrum's friend, the sheep, "and it didn't work."
"You have tried a revolt, and it failed?"
"No, no, another man tried to incite us to revolt, and failed."
