Whoever regards human beings as a herd and flees them as swiftly as he can will no doubt be overtaken by them and impaled on theirhorns.
Friedrich NietzscheExamine the life of the best and most productive men and nations, and ask yourselves whether a tree which is to grow proudly skywards can dispense with bad weather and storms. Whether misfortune and opposition, or every kind of hatred, jealousy, stubbornness, distrust, severity, greed, and violence do not belong to the favourable conditions without which a great growth even of virtue is hardly possible?
Friedrich Nietzsche
