“The jobs in the greatest demand in the future don't yet exist and will require workers to use technologies that have not yet been invented to solve problems that we don't yet even know are problems.”

“Science fiction is the arena of the not-yet, and every science fiction story has this element of not-yet-ness — usually a bit of technology or a scientific discovery that we don't know about in the real world of the present but that might be a possibility in the future.”

“I think of so many people who are no more, and I pity them. Yet they are not so much to be pitied, for they have solved every problem, beginning with the problem of death.”

“If people don't think they have the power to solve their problems, they won't even think about how to solve them.”

“The key is this: Meet today's problems with today's strength. Don't start tackling tomorrow's problems until tomorrow. You do not have tomorrow's strength yet. You simply have enough for today.”
