As Tim Wilson says, "We don't realize how quickly we will adapt to a pleasurable event and make it the backdrop of our lives. When any event occurs to us, we make it ordinary. And through becoming ordinary, we lose our pleasure."
To distill this even further, change never matters as much as we think it will. Knowing this, logically we should care less about change, craving good things a bit less while also fearing bad things a bit less.
Another interesting quote from the article:
George Loewenstein sums up this human capacity [of adaptation] as follows: "Happiness is a signal that our brains use to motivate us to do certain things. And in the same way that our eye adapts to different levels of illumination, we're designed to kind of go back to the happiness set point. Our brains are not trying to be happy. Our brains are trying to regulate us."
