Fail at love, and the other tests don't matter.

We all know those who draw their boundaries carefully and say, "I'm only human. Nobody's perfect. I accept my limitations." And we know others who take an opposite view and say, "I can do anything I choose to do. It is in my power to change the world." And those are the ones who most often change the world.

So much of what we said sounded crazy, yet none of it was false... as if two theoretical physicists stood on stage to say that when we travel near lightspeed, we get younger than nontravellers; that a mile of space next to the sun is differnt than a mile of space next to the earth because the sun-mile space is curved more than the the earth-mile. Silly ideas, worth the admission price in smiles, but they're true. Is high-energy physics interesting because it's true or because it's crazy?
