Book excerpt: Humans may be the most important beings on the planet, but they are also the most complex. This statement is true in more ways than one, humans are not the only living things on earth, but they are on top of the food chain because they embody intellectual prowess higher than other living things. As a human being, you think beyond eating and sleeping; you are always overwhelmed by so many other issues that must be dealt with daily, for you to experience the best out of life. However, dealing with these issues doesn't mean you get to escape the "complex" idea of your humanity. If you are going to deal with complexities all your life, the best thing you can do is understand them, and see how you can make the most out of the situation. The objective of this book is to share some of the most factual aspects of human complexity, so you are equipped with information that will help you live your best life now and understand your surroundings. We live in a world that is filled with diversity in many aspects, and these are the basic centre point of human nature. There is so much to learn on the issue of complexity, in fact, you will be amazed at the depths we will unravel, but I promise it will be fun all the way. "Humans had always been a complex mystery".
