I've had my Sansevieria trifasciata for about six months now and I'm still figuring out the watering schedule

I've had my Sansevieria trifasciata for about six months now and I'm still figuring out the watering schedule. I thought I was overwatering it, but then I realized my pot didn't have drainage holes—rookie mistake! Once I repotted it into something with proper drainage, the leaves actually started looking healthier. Has anyone else struggled with this, or am I just learning things the hard way?
