“Everyone has the right to doubt everything as often as he pleases and the duty to do it at least once. No way of looking at things is too sacred to be reconsidered. No way of doing things is beyond improvement.”

“We may have a perfectly adequate way of doing something, but that does not mean there cannot be a better way. So we set out to find an alternative way. This is the basis of any improvement that is not fault correction or problem solving.”

“You do not go out into the street in your underwear, although usually you are wearing underwear. The underwear is not visible but it is there all the time. It is the same with concepts. They are there. They underlie practical things we do- even when we are not conscious of them.”

“Critical thinking does seem a superior sort of thinking because it seems as though the critic is actually going beyond the scope of what is being criticized in order to criticize it. That is only rarely a true assumption because, most often, the critic will seize on some little aspect that he or she understands and tackle only that.”

“Creativity is a great motivator because it makes people interested in what they are doing. Creativity gives hope that there can be a worthwhile idea. Creativity gives the possibility of some sort of achievement to everyone. Creativity makes life more fun and more interesting.”

“A question is a polite way of demanding something.”

“The simple process of focusing on things that are normally taken for granted is a powerful source of creativity.”
