In the first part of the book, a summary of “How Children Succeed: Courage, Curiosity, and the Hidden Power of Character”. The first section “The Cognitive Hypothesis and the Holes It Contains” details chapters one and two. Part two, “The Power of Character,” details chapters one through five. Tough begins conveying his goals to the audience by beginning with “The Cognitive Hypothesis VS. The power of character.” The audience can be described as future and/or current educators, current education professionals, curious parents, and the general public. Difficult refers to the belief of the cognitive hypothesis as a strong belief that a child's future success depends on the development of mental skills and that the best way to develop these skills in children is to expose them to as many cognitive stimulation as possible and start as early as possible. He explains that there is evidence that establishes a strong correlation between success in primary school, university and post-employment after leaving school, with this hypothesis. The challenge with the cognitive hypothesis is that until about the age of ten, it was believed to be the only important ingredient contributing to a child's future success. Many studies have been done to investigate this claim and, shockingly, evidence has proven that there is in fact reason to believe that this hypothesis is not completely true.
