You finally did it.

You got the promotion, secured the raise, finished the project or otherwise leveled up in your career. It’s a wonderful feeling of accomplishment! You should be proud!

But then you come down from that high, and reality starts to sink in: Where do you go from here?

A little over a year ago, I drove home from the airport with the windows down and the radio on full blast after filming the last scenes for the Netflix docu-series “The Innocent Man.” I was so proud of the work I’d done investigating two wrongful murder convictions in a small city in Oklahoma in the 1980s. This was work that mattered, and I was thrilled to be a part of it.

A few days later, I sat in my truck and cried. An empty work schedule yawned before me, and I was sure that my most meaningful achievement was in my rearview mirror.

This wave of hopelessness has a name: I was experiencing arrival fallacy.

“Arrival fallacy is this illusion that once we make it, once we attain our goal or reach our destination, we will reach lasting happiness,” said Tal Ben-Shahar, the Harvard-trained positive psychology expert who is credited with coining the term.
