To achieve high productivity, a person must first be satisfied with life, because internal or external worries prevent them from handling tasks effectively. Making someone happy is a difficult task, but not an impossible one, if you understand how the brain works. This book offers a method that will allow you to radically change your life by giving you an understanding of how to manage your brain. I’ve never liked it when advice is given without explanations—just follow the instructions. Without a clear goal, it’s hard to act, but when you understand why you’re doing it, achieving your goals becomes easier.
