An insightful Aperture video reveals the sad reality that our happiness, or lack of, is always at a regular baseline. It only fluctuates slightly despite all our attempts at bliss and euphoria.

You wake up in the morning and go to work. You spend eight hours working away at your desk on a job you once loved but now kind of just tolerate. It's 5:00 p.m., you go home, eat dinner, and watch TV, only to do it all over again the next day. You play sports or catch up with friends on the weekend and life's good, but you still feel like something is missing.

Now imagine you get that well deserved promotion and a healthy raise and suddenly you're going on those vacations you once dreamt of. Driving a nicer car, receiving more status and respect in the workplace. Your quality of life has been significantly upgraded and finally you feel like you're fulfilling your potential. Fancy restaurants, rubbing elbows with influential people, your life feels new and almost foreign compared to where you came from.

Yet in a year or so your once brand-new Porsche just becomes your daily driver. All the imported sushi starts to taste the same and while you still frequent white sandy beaches and pristine ski slopes, these places have lost their allure.

You've completely changed your life but you're still in the same position you were in before you got the promotion. Those things that used to excite you have become stale, mundane, and boring. The reason why you'll never be happy is called “hedonic adaptation.” Hedonic adaptation is the tendency to return to a base level of happiness even when undergoing profound periods of positive or negative change.
