“You have to go for the quantum jumps.”

“When you have to jump, you jump.”

““I really liked that girl.”
“Not loved, evidently,” I observed.
“N-n-no. I supposed not. Though what is love, anyway? Doesn’t it have so infinitely many kinds and degrees and mutations and quantum jumps that— Never mind.””

“Although "jumping to conclusions" is an expression, rather than an activity, it is as dangerous as jumping off a cliff, jumping in front of a moving train, and jumping for joy. If you jump off a cliff, you have a very good chance of experiencing a painful landing unless there is something below you to cushion your fall, such as a body of water or an immense pile of tissue paper. If you jump in front of a moving train, you have a very good chance of experiencing a painful voyage unless you are wearing some sort of train-proof suit. And if you jump for joy, you have a very good chance of experiencing a painful bump on the head, unless you make sure you are standing someplace with very high ceilings, which joyous people rarely do. Clearly, the solution to anything involving jumping is either to make sure you are jumping to a safe place, or not to jump at all.”

“… You know the mistrust of heights is the mistrust of self, you don't know whether you're going to jump.”

“You have to jump into disaster with both feet.”

“By 78 you've done everything you're going to do. If you haven't bungee-jumped by the time you're 78 you're not going to do it.”

“It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.”

“I unbuckled my seat belt.
“Are you going to jump onto his car?” Julie asked. “I can get closer.”
“What are you, out of your mind? No, I’m not jumping on his car. That only works in movies.”

“I’m going to go ahead and go boldly
Cuz a little bird told me
That jumping is easy
That falling is fun
Right up ‘til you hit the sidewalk
Shivering and stunned.”
