There is a great difference between knowing and understanding: you can know a lot about something and not really understand it.

People are very open-minded about new things. As long as they are exactly like the old ones.

Problems are the price of progress. Don't bring me anything but trouble. Good news weakens me.

It's amazing what ordinary people can do if they set out without preconceived notions.

When I was research head of General Motors and wanted a problem solved, I'd place a table outside the meeting room with a sign: LEAVE SLIDE RULES HERE! If I didn't do that, I'd find some engineer reaching for his slide rule. Then he'd be on his feet saying, Boss you can't do that.

You can't have a better tomorrow if you are thinking about yesterday all the time.
