The birds are chirping, a warm breeze is blowing and some of your friends are getting vaccinated. After a year of anxiety and stress, many of us are rediscovering what optimism feels like. And the good news about an increase in available vaccines could not come at a more joyous time.

Spring is the season of optimism. With it comes more natural light and warm weather, both great mood boosters, and some of our most hopeful religious holidays: Easter, Passover, the Hindu festival of Holi and Nowruz, the Persian new year that celebrates springtime and renewal.

But if you’re expecting your happiness to skyrocket the moment we finish off this pandemic once and for all, think again.
