Endurance

"All daring and courage, all iron endurance of misfortune make for a finer, nobler type of manhood."

"Few people know how to take a walk. The qualifications are endurance, plain clothes, old shoes, an eye for nature, good humor, vast curiosity, good speech, good silence and nothing too much."

"At the end of the day it's about how much you can bear, how much you can endure. Being together, we harm nobody; being apart, we extinguish ourselves."
