I wrote How to Be Happy and made it free in hopes of reaching as many people as possible. It is my gift to you. If you would like to pay the gift forward, please contribute to The Girl Effect. This is an organization that raises money to educate girls in poverty-torn parts of the world. When women and girls earn income, they reinvest 90 percent of it into their families, as compared to only 30 to 40 percent for a man, so we can make a big difference!
