John Holt said this quote

Only to the degree that people have what they need, that they are healthy and unafraid, that their lives are varied, interesting, meaningful, productive, joyous, can we begin to judge, or even guess, their nature. Few people, adults or children, now live such lives.

~ John Holt

Leaders are not, as we are often led to think, people who go along with huge crowds following them. Leaders are people who go their own way without caring, or even looking to see, whether anyone is following them. Leadership qualities are not the qualities that enable people to attract followers, but those that enable them to do without them. They include, at the very least, courage, endurance, patience, humor, flexibility, resourcefulness, stubbornness, a keen sense of reality, and the ability to keep a cool and clear head, even when things are going badly. True leaders, in short, do not make people into followers, but into other leaders.

~ John Holt

A child whose life is full of the threat and fear of punishment is locked into babyhood. There is no way for him to grow up, to learn to take responsibility for his life and acts. Most important of all, we should not assume that having to yield to the threat of our superior force is good for the child's character. It is never good for anyone's character.

~ John Holt

If I had to make a general rule for living and working with children, it might be this: be wary of saying or doing anything to a child that you would not do to another adult, whose good opinion and affection you valued.
