Fall in love with the insane— Because crazy nevers leaves the honeymoon phase, sadness can always be romanticized, and appreciation stems from contrast.
Do not fall in love with the insane— Because you will never realize it, but you'll know it: that nothing sober will ever match up to psychotic intoxication, and you will always be living your life knowing you can't be satiated on sanity. You will settle, and you will be happy: But you will always be looking for the madness in people.
