This document summarizes Neil Pasricha's book "The Happiness Equation: Want Nothing + Do Anything = Have Everything". The book proposes that to be happy, one should first "Want Nothing" by focusing on internal goals and gratitude rather than external successes. Next, "Do Anything" by never retiring from activities you love and creating more free time and space. Finally, this will lead to "Have Everything" by focusing on internal motivation through action rather than advice from others and staying true to yourself.
