Each day in our life, we are always faced with situations that require us to make choices. Some are easy but there are some which are hard to decide. Most of the time, we make decisions quick enough we never thought about them not unless we realized we have made the wrong ones. Difficult decisions are those that require a deeper level of thinking like when we decide what course to take in college, who to marry, or what career to take. These decisions are often life-changing that we need to be more critical in our thinking. Making the wrong decisions over these matters can have an adverse and long-term effect on us and our future. Despite having to make so many decisions most of the time, it's likely that our parents failed to teach us about decision making and how to do it the smart way. It somehow became a common assumption that making a smart decision is a direct product of intelligent thinking and that it comes naturally. So when you're not born with high intelligence and you aren't a fast thinker, then you are most likely to make bad decisions. However, we need to establish first the relationship between intelligence, thinking fast, and being smart. Does this mean that when you are endowed with high intelligence, you can automatically think fast and make smart decisions? This book is geared towards establishing the relationship between intelligent thinking in correlation with theories of intelligence and decision making through quick-mind processing. As we establish the significance of fast-thinking process in making quality decisions, this book aims to teach you ways to develop your quick-thinking ability and smart decision making.
