“There are heroisms all round us waiting to be done.”

“My dear Watson," said [Sherlock Holmes], "I cannot agree with those who rank modesty among the virtues. To the logician all things should be seen exactly as they are, and to underestimate one's self is as much a departure from truth as to exaggerate one's own powers.”

“It may be that you are not yourself luminous, but that you are a conductor of light. Some people without possessing genius have a remarkable power of stimulating it.”

“When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.”

“He who has set his heart exclusively upon the pursuit of worldly welfare is always in a hurry, for he has but a limited time at his disposal to reach, to grasp, and to enjoy it.”

“The short space of threescore years can never content the imagination of man; nor can the imperfect joys of this world satisfy his heart. Man alone, of all created beings, displays a natural contempt of existence, and yet a boundless desire to exist; he scorns life, but he dreads annihilation. These different feelings incessantly urged his soul to the contemplation of a future state, and religion directs his musings thither. Religion, then, is simply another form of hope; and it is no less natural to the human heart than hope itself.”

"Change takes courage."

“Hard words are very rarely useful. Real firmness is good for every thing. Strut is good for nothing.”

“Tut, man, don't sprawl there. Get up and put your shoulder to the wheel.”

“If words suffice not, blows must follow.”

“Who acts in haste repents at leisure.”

“Try before you trust.”

“Little by little does the trick.”

“After all is said and done, more is said than done.”

“The great secret of education is to direct vanity to proper objects.”

“We are but one of the multitude, in no respect better than any other in it.”

“Mercy to the guilty is cruelty to the innocent.”

“Knowledge and action are very closely bound together, all agree. I go much further, and am convinced that knowledge and action are frequently synonymous, even identical in the Socratic fashion. Where we know fully and completely, suitable action follows automatically and reflexly. Choices are then made without conflict and with full spontaneity.”

“creativeness comes partly out of the unconscious, i.e., is a healthy regression, a temporary turning away from the real world.”

“One's only rival is one's own potentialities. One's only failure is failing to live up to one's own possibilities. In this sense, every man can be a king, and must therefore be treated like a king.”

“We fear our highest possibilities. We are generally afraid to become that which we can glimpse in our most perfect moments, under conditions of great courage. We enjoy and even thrill to godlike possibilities we see in ourselves in such peak moments. And yet we simultaneously shiver with weakness, awe, and fear before these very same possibilities.”

“It looks as if there were a single ultimate goal for mankind, a far goal toward which all persons strive. This is called variously by different authors self-actualization, self-realization, integration, psychological health, individuation, autonomy, creativity, productivity, but they all agree that this amounts to realizing the potentialities of the person, that is to say, becoming fully human, everything that person can be.”

“What one can be, one must be!”

“If you plan on being anything less than you are capable of being, you will probably be unhappy all the days of your life.”
