All-Round-Success hype--EVERYONE READING THIS BOOK HAS THE POWER TO CHANGE. EVERYONE. . . AND ESPECIALLY YOU CAN DEVELOP WINNING BEHAVIORS--from the author of Nice Girls Do. The means, with contrasts between winners and losers, are as usual: Decide what you want most; Learn from failure; Make your own luck; Replace negative with positive expectations, attitudes, ways-of-speaking. Plus: Share your feelings, face up to conflicts, etc. Role-models are proffered--from Harry Truman to Jessica Savitch to Norman Cousins. Some cases are cited, sometimes with concrete suggestions--how David overcame writer's block by sitting down at the typewriter and sticking to a schedule. Some standard psychological insights are presented--why Carl played up to other women at parties (to provoke Maxine into showing jealousy, to get reassurance of her love). Much is said about not being a motivation-killer, a squelcher--with a child, a spouse, a subordinate. Something is also said about getting 'round the squelchers, approaching their problems positively. It's not all slogans and inspirational patter. But Kassorla's chief distinction is her flamboyant packaging--in line with tales of her own boldness-pays success. ""In London I was a well-established media personality. I not only had a thriving private practice as a psychologist, but I appeared regularly on BBC radio and television. Having to start all over again as an intern in this country was disheartening."" Here's how ""the new intern"" got herself a posh office, a private secretary, and top-lever support. There'll be those who go for the image.
