" we can harness adaptation to maximize our overall satisfaction in life by shifting our investments away from products and services that give us a constant stream of experiences and toward ones that are more temporary and fleeting. For example, stereo equipment and furniture generally provide a constant experience, so it’s very easy to adapt to them. On the other hand, transient experiences (a four-day getaway, a scuba diving adventure, or a concert) are fleeting, so you can’t adapt to them as readily. I am not recommending that you sell your sofa and go scuba diving, but it is important to understand what types of experiences are more and less susceptible to adaptation. "
