"Make an experiment. Watch what happens when you ask someone a simple
question. In many cases the question could be answered yes or no, but
do you receive such a brief reply? Rarely. Give someone the slightest
opportunity to make a speech and they make a speech. This experiment
makes you more aware of human compulsion and nervousness, which helps
your own stability. A golfer noticing the wrong move of another player
does not make the same mistake himself."
