“Happiness is the final and perfect fruit of obedience to the laws of life.”

“The highest result of education is tolerance.”

“It all comes to this: the simplest way to be happy is to do good.”

“A happy life consists not in the absence, but in the mastery of hardships.”

“Optimism is the faith that leads to achievement; nothing can be done without hope.”

“No doubt the reason is that character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, vision cleared, ambition inspired, and success achieved.”

“You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, 'I have lived through this horror. I can take the next thing that comes along.' You must do the thing you think you cannot do.”

“You must not lose faith in humanity. Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty.”

“Strength does not come from physical capacity. It comes from an indomitable will.”

“The way in which a man accepts his fate and all the suffering it entails, the way in which he takes up his cross, gives him ample opportunity — even under the most difficult circumstances — to add a deeper meaning to his life.”

“There is nothing in the world, I venture to say, that would so effectively help one to survive even the worst conditions, as the knowledge that there is a meaning in one's life.”

“If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters.”
