Are you clever? Can you self-motivate? Are you creative? How do you handle money? Can you lead others well?

With their trademark style and wit, best-selling authors Mikael Krogerus and Roman Tschäppeler present sixty-four tests spanning intelligence and personality type; creativity and leadership skills; fitness and lifestyle; and knowledge and belief. From what you see in a Rorschach test to comparing your workout against a Navy SEAL's, from EQ to IQ and Myers-Briggs in between, The Test Book offers a panoply of ways to assess yourself and decide what you need to succeed. As Krogerus and Tschäppeler highlight, you can only know whether you have the right skills, the right job, or the right partner when you know where you stand right now.

Small enough to fit in your pocket but packed with insight and good humor, The Test Book delivers a quick, fun way to evaluate your life and happiness.

There's one truly great way to learn about ourselves and others: ask questions. The Question Book is just that, a book full of provocative questions, with space for you to answer. It canvasses a wide range of subjects, from the professional (How replaceable are you?) to the personal (Whose future do you have an influence on?) to the everyday (How much time do you spend on the Internet?). Intended to provoke short yes or no answers as well as open-ended responses, The Question Book can be used alone as a journal or as a conversation starter with a group of friends. Brief, direct, and compulsively fun to answer, each one of the more than 600 questions is an opportunity to gain insight and wisdom into our everyday lives.

From business cycles to budding trends, models make sense of a world that never stops spinning. The Change Book delivers 52 simple and effective models--each with a visual component--about how change happens.

Drawing on myth-busting theories and breakthrough discoveries from thinkers of all stripes, Mikael Krogerus and Roman Tschäppeler, authors of the international bestseller The Decision Book, apply their characteristic wit and knack for the succinct to show what fuels the internet, why empires rise and fall, and why change hurts--but ultimately helps us grow.

Whether you're starting a new job, lobbying for a cause, or wondering how Jesus would invest, The Change Book is your clever guide through transformations in business, culture, technology, relationships, and more.
