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

“Your success and happiness lie in you.”

“I have for many years endeavored to make this vital truth clear; and still people marvel when I tell them that I am happy. They imagine that my limitations weigh heavily upon my spirit, and chain me to the rock of despair. Yet, it seems to me, happiness has very little to do with the senses. If we make up our minds that this is a drab and purposeless universe, it will be that, and nothing else. On the other hand, if we believe that the earth is ours, and that the sun and moon hang in the sky for our delight, there will be joy upon the hills and gladness in the fields because the Artist in our souls glorifies creation. Surely, it gives dignity to life to believe that we are born into this world for noble ends, and that we have a higher destiny than can be accomplished within the narrow limits of this physical life.”

“Happiness does not come from without, it comes from within”

“Knowledge is power." Rather, knowledge is happiness, because to have knowledge - broad, deep knowledge - is to know true ends from false, and lofty things from low. To know the thoughts and deeds that have marked man's progress is to feel the great heart-throbs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.”

“Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.”

“What is true happiness? It's not attained through self-gratification but through fidelity to a worthy purpose.”
