We have identified the main ideas, named them, explained them in simple words, numbered them and given advice. Each paragraph introduces a new idea. We rated each idea on a scale of 0 to 10 based on its importance to society. You can gain wisdom from the book, starting with the most significant ideas. According to Pareto's Law, the first 20% of your main ideas can give you up to 80% of the benefit of a book. If you liked our work, please leave a review. We try our best for you.
