William Harry McRaven, a retired US Navy admiral, said, "If you want to change the world, start off by making your bed!" I say even if you don't care about changing the world and simply want to live a normal, simple, and happy life, you still need to make your bed. This bed is your thoughts, your ideas, your feelings, your beliefs, your knowledge, and your skills. This book is not complete instructions on how to make your bed. It's more an introduction to open the door for discussions and debates that will guide you regarding how to get it done in a way that suits you! A common idiom is "The devil is in the details," because within the details you face all distractions, unlike the goal that is clear and shiny. But on your way to the goal, you may get lost in those details! CHECKMATE will help you avoid these distractions by looking at the details differently. Following the strategy in this book will make the details to your goal not just a path but more like a journey, and that will help you not just walk through it but also enjoy it. Only then will you be able to deal with any problem with a smile-like this!
