“I do not think there is a demonstrative proof (like Euclid) of Christianity, nor of the existence of matter, nor of the good will and honesty of my best and oldest friends. I think all three are (except perhaps the second) far more probable than the alternatives. The case for Christianity in general is well given by Chesterton…As to why God doesn't make it demonstratively clear; are we sure that He is even interested in the kind of Theism which would be a compelled logical assent to a conclusive argument? Are we interested in it in personal matters? I demand from my friend trust in my good faith which is certain without demonstrative proof. It wouldn't be confidence at all if he waited for rigorous proof. Hang it all, the very fairy-tales embody the truth. Othello believed in Desdemona's innocence when it was proved: but that was too late. Lear believed in Cordelia's love when it was proved: but that was too late. 'His praise is lost who stays till all commend.' The magnanimity, the generosity which will trust on a reasonable probability, is required of us. But supposing one believed and was wrong after all? Why, then you would have paid the universe a compliment it doesn't deserve. Your error would even so be more interesting and important than the reality. And yet how could that be? How could an idiotic universe have produced creatures whose mere dreams are so much stronger, better, subtler than itself?”

“We are to work to improve ourselves while at the same time remaining totally dependent on God.”

“A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.”

“To be truly happy and fulfilled, you must be working toward accomplishing something that is bigger than yourself, and that makes a difference in the life or work of others.”

“At the moment that we persuade a child, any child, to cross that threshold, that magic threshold into a library, we change their lives forever, for the better”

“We see ourselves as self-sufficient, self-important, and self-sustaining. God sees us as dependent, self-centered, and self-deceived.”

“The first rule of frog eating is this: If you have to eat two frogs, eat the ugliest one first.”

“What can you do with a man who has an invincible purpose in him; who never knows when he is beaten; and who, when his legs are shot off, will fight on the stumps. Difficulties and opposition do not daunt him. He thrives upon persecution; it only stimulates him to more determined endeavor. The world always listens to a man with a will in him.”

“God always takes the simplest way.”

“I will not let anyone walk through my mind with their dirty feet.”

“Don't go in for the "yellowish" if what you need is "yellow". The attitude called precision is the quality that remarks the accuracy of your demand. Never settle for the less; Go for the exact thing!”

“You will never change what you tolerate.”

“The best way to predict your future is to create it.”

“Stop for a few seconds and create a clear mental picture of yourself as completely relaxed, calm, positive, smiling, and in complete control of the interview. Then inhale deeply, filling up your lungs and putting pressure on your diaphragm. Hold this breath for a count of seven and exhale for a count of seven. While you are breathing deeply, continue to hold a picture of yourself as the very best salesperson you could possibly be.”

“Todo está en tu mente Cualquier cosa que albergues en tu mente tenderá a suceder en tu vida. Si continúas creyendo como siempre has creído, continuarás actuando como siempre has actuado. Si continúas actuando como siempre has actuado, continuarás obteniendo lo que siempre has obtenido. Si quieres resultados diferentes en tu vida o en tu trabajo, lo único que tienes que hacer es cambiar tu mentalidad.”
