A new quote I added to my Favorite Quotes page (from Art De Vany’s website):
"Complex systems don't have causes. There are just patterns and at any point one's state of health can move randomly onto a new path. It is not the particular path that one should think about. You move over an ensemble of possible paths, conditional on how you live and the choices you make. All you can do is to try to influence the distribution of possibilities. You can never set the particular path or outcome that will be yours from this time forward. If you think you can look back and see some cause of events, you are probably suffering hindsight bias or what I call complexity blindness.
Think of the freedom this view gives you. There is no possibility of failure because you only control your actions and they only influence the probable evolution of your life over stochastic future paths. There is no failure, only feedback." –Art De Vany
