" Success in life, no matter what one may call success, is very largely a matter of adaptation to environment in such a manner that there is harmony between the individual and his environment. The palace of a king becomes as a hovel of a peasant if harmony does not abound within its walls. Conversely stated, the hut of a peasant may be made to yield more happiness than that of the mansion of the rich man, if harmony obtains in the former and not in the latter. "
