Happiness

Happiness is becoming a huge area in psychological research and even in government policy, with the UK government exploring a "happiness index". It's tough, though, to define exactly what happiness is, and what makes us happy.

There are two broad ways of looking at happiness: short-term happiness ( a great cookie, a boodle of wine) and long-term happiness ( financial security, achieving your goals). Both types of happiness are valid, and important. The problem is, they're often in competition.

Let's say you've got a goal of losing 50 pounds this year. You know you'd be happier and healthier if you weren't carrying that extra weight. To achieve long-term happiness, you need to go on a diet. In the short-term, though, it's not that easy. A chocolate cake, or a large glass of wine, might seem like just the thing to cheer you up at the end of a long day or to celebrate with friends. It's the same with lots of other goals.

If you've got a tendency to prioritize long-term happiness at the expense of day-to-day pleasures, you should start looking for some small ways to bring a little joy back into your life. I'm not suggesting that you go our and get drunk every night, or that you stuff with cake. There are plenty of other ways to enjoy yourself. Don't pin all your hopes of happiness on some far-off future, though. There's no point working a 60-hour week and making yourself thoroughly miserable in the belief that things will be prefect as soon as you're making a six-figure salary.

A．Happy Thereafter
