The rallying cry among those of us who ascribe to voluntary simplicity is "Things don't make us happy." Why, then, are materialistic habits so hard to break?

In The How of Happiness, Sonja Lyubomirsky both challenges and supports that rallying cry. She explains that money and possessions do make us happier...for a little while. If you by a brand new car or whatever else you've been craving, then your happiness levels receive an immediate boost. But that boost only lasts for a short period of time, at which point you tend to drop down to your normal happiness level.

Why? Because humans are extremely adaptable. Lose a leg, and within a couple of years the majority of amputees are just as happy as they were pre-surgery. Win the lottery, and that immediate elation is long gone by the end of twelve months. Even getting married --- which I've seen in other studies linked to long-term increases in health and happiness --- is only supposed to raise you above your own average happiness level for about two years.

These examples are all types of hedonistic adaptation --- the human tendency to get used to both positive and negative changes in our lives. The good news is, you can counteract hedonistic adaptation, drawing out the positive effects of everything from that new handbag to that new spouse.

It takes conscious effort to extend the honeymoon period so you can keep savoring and appreciating the wonder of having fun-loving goats and cute, cuddly chicks on your farm, but the project is definitely worth the time. Similarly, if you've got some money to spend and want to go out and buy something new to make you happy, try selecting experiences instead of physical objects, and do so in small doses spread throughout the year rather than in one big chunk.

Or just be aware of your own tendency toward hedonistic adaptation and ask yourself --- "how long will that new wardrobe make me happy, and is that short boost in mood worth the expense?" The awareness just might be enough to help you achieve your goal of voluntary simplicity.
