Happiness = (Time spent being grateful for what we have) / (Time spent thinking about what we don’t have)
Implications of this theory:
(1) The more the gratitude, the more the happiness. This follows the idea that it isn’t happy people who are thankful, it is thankful people who are happy.
(2) Reducing time spent thinking about what we don’t have can have an infinite impact on our happiness if we can bring it down to zero.
