hello there, if you’re reading this then this is an message by the creator of this book which my name is justin diaz, you may be thinking is this a joke or a message, well as it says in the title this book is about how to use your brain and how we people use it in our everyday lives and this is a saying on how and why we have a brain. but you probably could be a teacher, student, parent, astronaut, businessman, or anything else that there is, remember our brain could make up random jobs or workplaces that don’t exist or maybe do. you probably think that this is a twenty-seven-year-old just writing a random book just to make money to buy things. but this isn’t our normal author, this is a 13-year-old. “what a 13-year-old” when you were a 13-year-old what were you doing, maybe you are not a 13-year-old, or maybe you are about to be 13 years old, or maybe you are a 13-year-old maybe you are younger than that, remember there many people out there in the world that have many different hobbies to do. maybe even assigned, but there is many different ways to control out mind, but with this out of the way let's gets on the topic of this book, remember you have the ability to go on reading this or not so let's continue the topic of this book “no questions asked’’.
