To talk about happiness means talking about an illusion, a goal in life, something very desirable but at the same time ephemeral. At least if we are referring to the idealized "happiness" sold through commercials, television or radio. But happiness is much more than achieving a desired goal in particular; it is a daily effort to maintain that state, otherwise, what would be the purpose of achieving happiness if we have to lose it afterwards? In this book you will find the latest investigations related to happiness and the answers to what it is and how to achieve it. You will also find what happens if you don't achieve happiness and what happens when the inconveniences and barriers to achieving happiness appear. It will all be explained in a clear and simple way in order to offer you an enriching experience that will be able to help you in your personal search for achieving happiness; but a happiness that will be real, possible and attainable, and above all, lasting.
