As it turns out, Bobby McFerrin was right when penned the hit song, “Don’t Worry, Be Happy.”

Misery: it’s everywhere these days. We are all popping happy pills like Smarties, checking ourselves into clinics and stocking up on happiness books. But for every report telling us it is all down to our ever-longer working hours, additive-laden food and endless commutes, there is a growing body of scientific research suggesting that happiness is, quite literally, a state of mind.

“You have to decide to be happy,” says Paul Jenner, author of Teach Yourself Happiness. “Most people think happiness is something that arrives by itself, like rain. But it isn’t. Barring seriously depressed people, most Westerners have plenty to be happy about, but they choose to focus on things they haven’t got. It really is that simple.”

Scientific research is starting to back up this idea. Rather than happiness being something we earn through circumstances, it seems we can work at it in the same way we work our bodies at the gym, reaching beyond our “genetic set point”, the predisposition to happiness (or unhappiness) we were born with.

According to Sonja Lyubomirsky, psychology professor at the University of California, Riverside, who has been researching happiness, there is converging evidence that some people are born happier than others, but that all of us can learn to raise our happiness levels.
How do we do this? By adopting certain exercises - or “happiness strategies” - that Lyubomirsky, in her tests, found very effective in perking people up.

“People born with a high set point will do these ‘happiness strategies’ automatically, and we all know people like that - they naturally look on the bright side and are good at maintaining relationships - but if it doesn’t come naturally, we have to work at it, in the same way someone who is genetically determined to be overweight has to watch their diet and exercise,” she tells The Guardian.

This issue of “working at it” is crucial to Lyubomirsky’s approach. She has discovered that timing and persistence are crucial. Do the exercises too often and you may get bored; don’t do them often enough, and they may not make a difference.

 

So can a negative person really become happier through adopting these strategies? Lyubomirsky thinks so. “If you work at it, it becomes a habit. Something I want to explore in the future is whether the exercises can become so habitual that we automatically begin to think in more positive ways.”

The first thing to do is step off the “hedonic treadmill”: that constant hunger for new acquisitions and experiences. It is seductive but leaves people hankering for more. “The hedonic treadmill is one of the major barriers to happiness,” says Lyubomirsky. One way to counter it, she says, is to invest meaning in goals that we adapt to less easily, “things that challenge and surprise us”, rather than static things such as money and possessions. “Because if you adapt to everything positive that happens to you, how can you raise and maintain your happiness levels?”

Lyubomirsky calls goals “dynamic happiness strategies”. They are things such as learning a language, taking up exercise, trying to be more forgiving, or focusing more on spiritual or philosophical beliefs (well-known happiness boosters).

No-nos include comparing ourselves to other people and negative rumination (“in a way that doesn’t problem-solve”). “Research shows that constant rumination on negative events is linked to depression,” she explains. “If you are mildly depressed, it will depress you even more.”Can moaning ever be useful? Perhaps, says Nicky Page, of Britain’s Centre for Applied Positive Psychology, citing research that to be a “high-performing team” you need three positive interactions (approvals) to one negative interaction (disagreement). “The point is that you need that negativity, otherwise you become a back-slapping loop that can’t look at itself objectively.”

What most psychologists agree on is that putting our thoughts into writing is useful. “Writing about your goals gives you an opportunity to learn about who you really are,” says Lyubomirsky.
