What this says is that experience is not always the best teacher. Sometimes it closes us down. Both in school and at home we are taught a reliance on authority, on the opinions of others. Sometimes just pointing at what is going on is a valuable way to break through a barrier. Education, on the other hand, leads not to technique but to information and knowledge, which in the right hands can lead to understanding, even to wisdom.
Training makes people more alike, because everyone learns the same skills.
Education, because it involves an examination of one's personal experience in the light of an encounter with great ideas, tends to make people different from each other. So the first benefit of education is that the manager becomes unique, independent, the genuine article. Amateur' stems from the Latin word amator, which means 'lover'. Amateurs do what they do out of love. That is a word that does not often arise in conversation about management development, yet love is fundamental to good leadership, because leadership is all about caring.
