When I was creating this book, I worked closely with lectors who wrote the chapters to ensure not to misrepresent their ideas and message. The book consists of eleven chapters and contains more than 160 unique illustrations and many more exercises, graphs, and visuals. The Academy of Critical Thinking approaches each client individually, according to their needs, and I chose the same approach when creating this handbook. I created a printed version, but also an interactive version for online learning sessions. As the courses of the Academy are tailor-made specifically according to the needs of the clients, the book adapts as well. Each chapter can be printed or exported separately, so the clients get only the materials they really need. Additionally, I also designed a line of merchandise that uses illustrations, quotations, and ideas from the handbook.
