"The best teacher, until one comes to adult pupils, is not the one who knows most, but the one who is most capable of reducing knowledge to that simple compound of the obvious and the wonderful which slips into the infantile comprehension. A man of high intelligence, perhaps, may accomplish the thing by a conscious intellectual feat. But it is vastly easier to the man (or woman) whose habits of mind are naturally on the plane of a child's. The best teacher of children, in brief, is one who is essentially childlike."
H.L Mencken, journalist...from Teachers Are Special
