My book The Happiness Project came out almost ten years ago—wow, that’s hard to believe.
One of the most important things I learned as part of doing that project, and an idea that I put into practice in my own life all the time, is that I can influence my happiness. Yes of course, sometimes terrible circumstances make it impossible for me to be happy, but it’s almost always possible to be happier, and often with just a few small steps, I can give myself a big boost.
