“There are more kinds of fools than one can guard against.”

“I am quite willing to be the blind instrument of higher ends. To give one's life for the cause is nothing. But to have one's illusions destroyed - that is really almost more than one can bear.”

“Avoid irritation more than exposure to the sun...In the tropics one must before everything keep calm.' . . .”

“No fear can stand up to hunger, no patience can wear it out, disgust simply does not exist where hunger is; and as to superstition, beliefs, and what you may call principles, they are less than chaff in a breeze. Don't you know the devilry of lingering starvation, its exasperating torment, its black thoughts, its sombre and brooding ferocity? Well, I do. It takes a man all is inborn strength to fight hunger properly. It's really easier to face bereavement, dishonour, and the perdition of one's soul - than this kind of prolonged hunger. Sad, but true.

Or you may be such a thunderingly exalted creature as to be altogether deaf and blind to anything but heavenly sights and sounds. Then the earth for you is only a standing place—and whether to be like this is your loss or your gain I won’t pretend to say. But most of us are neither one nor the other.”

“These little things make all the great difference. When they are gone you must fall back upon your own innate strength, upon your own capacity for faithfulness. Of course you may be too much of a fool to go wrong--too dull even to know you are being assaulted by the powers of darkness. I take it no fool ever made a bargain for his soul with the devil. The fool is too much of a fool or the devil too much of a devil--I don't know which. Or you may be such a thunderingly exalted creature as to be altogether deaf and blind to anything but heavenly sights and sounds. Then the earth for you is only a standing place--and whether to be like this is your loss or your gain I won't pretend to say. But most of us are neither one or the other.”
