Moderation, which consists in indifference about little things, and in a prudent and well-proportioned zeal about things of importance, can proceed from nothing but true knowledge, which has its foundation in self-acquaintance.
For unless one is able to live fully in the present, the future is a hoax. There is no point whatever in making plans for a future which you will never be able to enjoy. When your plans mature, you will still be living for some other future beyond. You will never, never be able to sit back with full contentment and say, "Now, I've arrived!" Your entire education has deprived you of this capacity because it was preparing you for the future, instead of showing you how to be alive now.
We do not want joy and anger to neutralize each other and produce a surly contentment; we want a fiercer delight and a fiercer discontent. We have to feel the universe at once as an ogre's castle, to be stormed, and yet as our own cottage, to which we can return to at evening.
