15 ways to boost self confidence and love the way you look, according to scientists

Women in America are really unhappy with their weight.

About 84% want to lose weight and 34% say that what they eat or how much they weigh is interfering with their happiness, according to Happify — a website and app that uses games and tasks based on scientific studies in positive psychology to make you feel happier.
