"There are no perfect human beings! Persons can be found who are good, very good indeed, in fact, great. There do in fact exist creators, seers, sages, saints, shakers, and movers...even if they are uncommon and do not come by the dozen. And yet these very same people can at times be boring, irritating, petulant, selfish, angry, or depressed. To avoid disillusionment with human nature, we must first give up our illusions about it."
