“When I was a boy a farmer's wife who lived five miles from our village had great fame as a faith-doctor—that was what she called herself. Sufferers came to her from all around, and she laid her hand upon them and said, "Have faith—it is all that is necessary," and they went away well of their ailments. She was not a religious woman, and pretended to no occult powers. She said that the patient's faith in her did the work. Several times I saw her make immediate cures of severe toothaches. My mother was the patient. In Austria there is a peasant who drives a great trade in this sort of industry, and has both the high and the low for patients. He gets into prison every now and then for practising without a diploma, but his business is as brisk as ever when he gets out, for his work is unquestionably successful and keeps his reputation high. In Bavaria there is a man who performed so many great cures that he had to retire from his profession of stage-carpentering in order to meet the demand of his constantly increasing body of customers. He goes on from year to year doing his miracles, and has become very rich. He pretends to no religious helps, no supernatural aids, but thinks there is something in his make-up which inspires the confidence of his patients, and that it is this confidence which does the work, and not some mysterious power issuing from himself.”

“Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.”

“Only the scum of the population do it”

As quoted in Roughing It http://www.friesian.com/quotes.htm (1872).
Roughing It (1872)
Context: No California gentleman or lady ever abuses or oppresses a Chinaman, under any circumstances, an explanation that seems to be much needed in the east. Only the scum of the population do it; they and their children. They, and, naturally and consistently, the policemen and politicians, likewise, for these are the dust-licking pimps and slaves of the scum, there as well as elsewhere in America.

“I do not wish any reward but to know I have done the right thing.”
