«Cuando digo no, me siento culpable» is the self-help manual by Manuel J. Smith, published by Grijalbo in paperback (438 pages, in Spanish).
The book presents systematic assertive therapy, a behaviourist-based method for learning to say no without guilt. It analyses manipulation in family, social and work settings, and proposes techniques to assert one's own rights and reduce defensive reactions in everyday communication.
Published in 1986 in the Self-Help and Improvement collection (no. 91). Translation by Ramón Hernández Sol from the original English; bibliography on pp. 435-436.
For readers of personal development and practical psychology interested in assertiveness, communication and personal and work boundaries.
John Maynard Smith was a British theoretical and mathematical evolutionary biologist and geneticist. Originally an aeronautical engineer during the Second World War, he took a second degree in genetics under the biologist J. B. S. Haldane. Maynard Smith was instrumental in the application of game theory to evolution with George R. Price, and theorised on other problems such as the evolution of sex and signalling theory.
