“You don’t have to be psychic to end up knowing things you were a lot happier not knowing.”
“…You don’t want the best of times to be just one thing, forever. You have to have a lot of bests of times, each one topping the last. You know?”
“...why were you happier when you were a kid? Because you didn't know anything. The more you know, the sadder you get.”
“If you don't know what you want," the doorman said, "you end up with a lot you don't.”
“Check-ups are, in my experience, a grave mistake; all they do is allow the quack of your choice to tell you that you have some sort of complaint that you were far happier not knowing about.”
“If you don’t know exactly where you are going (and why),that is exactly where you will end up.”
