The only thing that makes life possible is permanent, intolerable uncertainty; not knowing what comes next.
—Ursula K. Le Guin
If we can recognize that change and uncertainty are basic principles, we can greet the future and the transformation we are undergoing with the understanding that we do not know enough to be pessimistic.
When nothing is for sure, we remain alert, perennially on our toes. It is more exciting not to know which bush the rabbit is hiding behind than to behave as though we knew everything.
No man can ever be secure until he has been forsaken by Fortune.
I believe that uncertainty is really my spirit's way of whispering, "I'm in flux. I can't decide for you. Something is off-balance here.
—Pliny the Elder
Sometimes things don't turn out the way you want them to. Sometimes the people you choose to believe are wrong.
—Sarah Dessen in That Summer
The world is noisy and messy. You need to deal with the noise and uncertainty.
There ain't no answer. There ain't gonna be any answer. There never has been an answer. That's the answer.
Research is what I'm doing when I don't know what I'm doing.
—Wernher von Braun
