“Self-discipline without talent can often achieve astounding results, whereas talent without self-discipline inevitably dooms itself to failure.”

“The generality of mankind is lazy. What distinguishes men of genuine achievement from the rest of us is not so much their intellectual powers and aptitudes as their curiosity, their energy, their fullest use of their potentialities. Nobody really knows how smart or talented he is until he finds the incentives to use himself to the fullest. God has given us more than we know what to do with.”

“It’s surprising how many persons go through life without ever recognizing that their feelings toward other people are largely determined by their feelings toward themselves, and if you’re not comfortable within yourself, you can’t be comfortable with others.”

“The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, "I was wrong.”

“Wealth is more often the result of a lifestyle of hard work, perseverance, planning, and, most of all, self-discipline.”

“The principal difference between love and hate is that love is an irradiation, and hate is a concentration. Love makes everything lovely; hate concentrates itself on the object of its hatred. All the fearful counterfeits of love — possessiveness, lust, vanity, jealousy — are closer to hate: they concentrate on the object, guard it, suck it dry.”

“Patriotism is proud of a country's virtues and eager to correct its deficiencies; it also acknowledges the legitimate patriotism of other countries, with their own specific virtues. The pride of nationalism, however, trumpets its country's virtues and denies its deficiencies, while it is contemptuous toward the virtues of other countries. It wants to be, and proclaims itself to be, "the greatest", but greatness is not required of a country; only goodness is.”
