Best-selling author Arthur C. Brooks is an expert on happiness research. But he also honestly shares about his own struggle with finding true satisfaction in life:

I have fallen into the trap of believing that success would fulfill me. On my 40th birthday I made a bucket list of things I hoped to do or achieve. They were mainly accomplishments only a wonk could want: writing books and columns about serious subjects, teaching at a top school, traveling to give lectures and speeches, maybe even leading a university or think tank. Whether these were good and noble goals or not, they were my goals, and I imagined that if I hit them, I would be satisfied.

I found that list when I was 48 and realized that I had achieved every item on it. But none of that had brought me the lasting joy I’d envisioned. Each accomplishment thrilled me for a day or a week—maybe a month, never more—and then I reached for the next rung on the ladder.

I’d devoted my life to climbing those rungs. I was still devoting my life to climbing—working 60 to 80 hours a week to accomplish the next thing, all the while terrified of losing the last thing. The costs of that kind of existence are obvious, but it was only when I looked back at my list that I genuinely began to question the benefits—and to think seriously about the path I was walking.

And what about you? Your goals are probably very different from mine, and perhaps your lifestyle is too. But the trap is the same. Everyone has dreams, and they beckon with promises of sweet, lasting satisfaction if you achieve them. But dreams are liars. When they come true, it’s … fine, for a while. And then a new dream appears.
