I want to leave a legacy, something that is useful for the world. I don't want to write a random book, I want to write a book that adds exponential value to anyone who reads it. I want to write a book that will be used as a reference book for many generations to come. I need to write this book so that the world will use it extensively. I don't want to write an entertaining novel and pulp fiction. I want to write a book that is easy to read and also add value in the process. @boniaditya
