This book is based on a mix of scientific research into happiness psychology and the author's own personal experience.
People tend to overestimate how much happiness a future event will bring them, and how long that happiness will last. The truth is, no single life event can bring about lasting happiness. Lasting happiness comes from inner happiness developed from within.
You cannot control what happens to you or around you, but you can control you.
This book includes practical instructions on how to improve your baseline (day to day) happiness level based on scientific evidence.
So go ahead and make yourself happy today. What have you got to lose?
