As a human being you may have the choice of three basic attitudes towards life. You may treat life with the philosophy (哲学) of the vegetable, in which case your life will include being born, eating, drinking, sleeping, marrying, growing old and dying. The second basic attitude is to look at life as if it were a business. A great many so-called successful men and women believe that life is a business. If you believe so, your first question of life, naturally, is ' What do I get out of it? ' ' How much is this worth to me?' In a word, based on this attitude, happi­ness becomes a matter of successful competition. The great ma­jority of human beings today look at life as if it were a busi­ness. The third attitude toward life is the way of the artist. Here the basic philosophy is 'What can I put into it?'. They value cooperation and contribution. This point of view has been proved by history; for history remembers best those who have contributed most richly to the interests of their fellow-men. The more we investigate(调查),the more we become certain that the artistic attitude is the only one which goes with human happiness. 5.
