After years teaching courses for people and companies to communicate better, journalist and communication professor Alfred Picó has decided to go into the dark side. In this book he teaches everything you shouldn’t do. Send eternal audios, write infinite emails, give out soporific speeches, turn group chats into hell or misinform with admirable Effectiveness.

An essential guide to provoke misunderstandings, spread chaos, and exasperate friends, customers, and co-workers.
