"Men in general are too material and do not make enough human contacts. If we search for the fundamentals which actually motivate us we will find that they come under four headings: love, money, adventure and religion. It is to some of them that we always owe that big urge which pushes us onward. Men who crush these impulses and settle down to everyday routine are bound to sink into mediocrity. No man is a complete unit of himself; he needs the contact, the stimulus and the driving power which is generated by his contact with other men, their ideas, and constantly changing scenes."
