How can experience and knowledge make each individual unique?

Personal experience—both good and bad—can teach us valuable lessons. But is it true that experience is the best teacher, as the saying goes, No, there is a superior source of guidance. The effect on the inexperienced one seeing the reward of making wrong decisions he could ‘become wise’ and determine not to follow such a course as to repeat them.
By way of contrast, “a wise person” already knows from past experience, observation, and knowledge making wrong decisions. However He does not always need to observe the ruinous outcome of a certain act to be convinced of its wrongfulness. A person can gain new ‘insights’ by mere instruction, rather than by bitter experience.
PROVERBS 21:11 says: “By the laying of a fine on the ridiculer the inexperienced becomes wise; and by one’s giving insight to a wise person he gets knowledge.”
