Lonely dissent doesn't feel like going to school dressed in black. It feels like going to school wearing a clown suit. - Eliezer Yudkowsky

Rationality is the master lifehack which distinguishes which other lifehacks to use.

Ever since I adopted the rule of "That which can be destroyed by the truth should be," I've also come to realize "That which the truth nourishes should thrive." When something good happens, I am happy, and there is no confusion in my mind about whether it is rational for me to be happy. When something terrible happens, I do not flee my sadness by searching for fake consolations and false silver linings. I visualize the past and future of humankind, the tens of billions of deaths over our history, the misery and fear, the search for answers, the trembling hands reaching upward out of so much blood, what we could become someday when we make the stars our cities, all that darkness and all that light — I know that I can never truly understand it, and I haven't the words to say.

There are no surprising facts, only models that are surprised by facts; and if a model is surprised by the facts, it is no credit to that model.
