But the worst enemy you can meet will always be yourself; you lie in wait for yourself in caverns and forests. Lonely one, you are going the way to yourself! And your way goes past yourself, and past your seven devils! You will be a heretic to yourself and witch and soothsayer and fool and doubter and unholy one and villain. You must be ready to burn yourself in your own flame: how could you become new, if you had not first become ashes?
He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you.
I can never read all the books I want; I can never be all the people I want and live all the lives I want. I can never train myself in all the skills I want. And why do I want? I want to live and feel all the shades, tones and variations of mental and physical experience possible in life. And I am horribly limited.
