We have more choices than we realize. In fact, according to positive psychology expert Tal Ben-Shahar, our entire life is made of choices, large and small. It is what we choose moment by moment and day by day--to do, to feel, to experience--that determines how happy and fulfilled we are. Every moment, then, is an opportunity to make a choice that will bring us greater happiness. Ben- Shahar presents 100 such opportunities, some simple, such as whether to frown or smile, others complex, such as whether to hold on to what we know or change our perspective--helping us identify them, recognize their importance, and make the right choice. Each choice includes a brief explanation plus a story or study that makes it accessible and relatable. It's up to you to choose the life you want!
