Believe me, the secret to reaping the greatest fruitfulness and the greatest enjoyment from existence is to live dangerously! Build your cities by Vesuvius! Send your ships into unexplored seas! Live at war with your fellows and with yourselves! Be robbers and conquerors, as long as you cannot be rulers and possessors, you knowing ones! The time is nearly gone when it could be enough for you to live hidden in the woods like a shy deer! At last knowledge will reach out its hand for what is due to it - it will want to rule and possess, and you will too, along with it!
Nietzsche, Gay Science
