Everybody knows someone like Harry Smith. He's the kind of guy who, at the drop of a hat, can tell you exactly what's wrong with everything - his friends, his wife, his company, even you. He rarely points the finger, though, at himself. It's a safe bet that Harry is an unhappy person. He doesn't get along well with most people. He's not getting ahead on his job fast enough to suit himself. Harry's personal appearance is usually sloppy. His shoes are rarely shined; his shirts and suits aren't usually clean. he often needs a haircut. Though appearance isn't all-important, it does reveal Harry's basic trouble. His whole attitude toward other people is one of "not caring," of self-centeredness.
