Jim Kwik, the author, was born with a catastrophic brain injury, which he sustained as a kid. It caused him to have a learning disability, which meant he had to work much harder than the other students to succeed in school.On top of that, he was subjected to a great deal of bullying. Even a teacher reportedly referred to him as "the kid with the shattered brain" because of his condition. For years, the author believed that, as a result of his disability, he would have to put in a lot of effort to learn new things. Kwik, on the other hand, discovered that there was another route while in college. He didn't need to work harder; he just needed to study more effectively. The techniques he discovered enabled him to sharpen his concentration, enhance his memory, and begin to absorb materials at a quicker rate than he had ever done before.
