Happiness is the universal feeling we all aspire to experience more of, yet, we can be an angry, moody, depressed bunch, can’t we? The science of happiness tells us that being happy is, indeed, a choice.

It seems as if every week we hear about a new tragedy that makes us question the human spirit. Unfortunately, we live in a world where there will inevitably be war, famine, poverty, and destruction. But here’s the thing: good always trumps evil. The actions of one happy person can create a ripple effect that can literally change the world. So be the change you wish to create. Choose happiness. Be happy for this moment. This moment is your life.

No matter how sick, tired, sad, or unhappy you are, there’s one thing you can still be grateful for and that’s the fact that you’re still here. People we love leave us unexpectedly on a regular basis. Think about what you would do if you knew this was your last day on earth?
