“If you fail, as men have failed in their quest for a vision that should have been possible, yet has remained forever beyond their reach — if, like them, you come to think that one’s highest values are not to be attained and one’s greatest vision is not to be made real — don’t damn this earth, as they did, don’t damn existence. You have seen the Atlantis they were seeking, it is here, it exists — but one must enter it naked and alone, with no rags from the falsehoods of centuries, with the purest clarity of mind — not an innocent heart, but that which is much rarer: an intransigent mind — as one’s only possession and key. You will not enter it until you learn that you do not need to convince or to conquer the world. When you learn it, you will see that through all the years of your struggle, nothing had barred you from Atlantis and there were no chains to hold you, except the chains you were willing to wear. Through all those years, that which you most wished to win was waiting for you” — he looked at her as if he were speaking to the unspoken words in her mind — “waiting as unremittingly as you were fighting, as passionately, as desperately but — with a greater certainty than yours. Go out to continue your struggle. Go on carrying unchosen burdens, taking undeserved punishment and believing that justice can be served by the offer of your own spirit to the most unjust of tortures. But in your worst and darkest moments, remember that you have seen another kind of world. Remember that you can reach it whenever you choose to see. Remember that it will be waiting and that it’s real, it’s possible — it’s yours.” (Atlas Shrugged, Ayn Rand)
