I've had my ZZ plant for about eight months now and I'm finally starting to trust that I'm not overwatering it

I've had my ZZ plant for about eight months now and I'm finally starting to trust that I'm not overwatering it. I keep second-guessing myself because it looks so sturdy and unbothered that I worry it's secretly suffering, but I think that's just the ZZ being its reliable self. The new leaflets coming in are making me feel like maybe I'm actually getting the hang of this. Has anyone else had that moment where they realised their plant was fine all along and they were just anxious?
