Who said “Never tire yourself more than necessary, even if you have to found a culture on the…”?

“Our greatest weariness comes from work not done.”

“Nothing is so fatiguing as the eternal hanging on of an uncompleted task.”

“Fatigue makes cowards of us all.”

“Our fatigue is often caused not by work, but by worry, frustration and resentment.”

“Fatigue dulls the pain, but awakes enticing thoughts of death. So! that is the way in which you are tempted to overcome your loneliness -- by making the ultimate escape from life. -- No! It may be that death is to be your ultimate gift to life: it must not be an act of treachery against it.”

“No one has ever written, painted, sculpted, modeled, built, or invented except literally to get out of hell.”

“Hell is of this world and there are men who are unhappy escapees from hell, escapees destined ETERNALLY to reenact their escape.”

“It is not opium which makes me work but its absence, and in order for me to feel its absence it must from time to time be present.”

“So long as we have failed to eliminate any of the causes of human despair, we do not have the right to try to eliminate those means by which man tries to cleanse himself of despair.”

“When we speak the word ''life,'' it must be understood we are not referring to life as we know it from its surface of fact, but to that fragile, fluctuating center which forms never reach.”

“There is in every madman a misunderstood genius whose idea, shining in his head, frightened people, and for whom delirium was the only solution to the strangulation that life had prepared for him.”
