When we push away joy, we squander the goodness that we need to build resilience, strength, and courage. The good news? In our research we found that everyone who showed a deep capacity for joy had one thing in common: They practiced gratitude. In the midst of joy, there’s often a quiver, a shudder of vulnerability. Rather than using that as a warning sign to practice imagining the worst-case scenario, the people who lean into joy use the quiver as a reminder to practice gratitude.
