struggling with keeping houseplants alive

i've always loved the idea of having a home full of beautiful green plants. they just add such a nice vibe and freshness to any space, right? but for some reason, no matter what i try, i can't seem to keep them alive for more than a few weeks. i've tried succulents, ferns, and even those 'un-killable' snake plants. they all end up looking sad and droopy. maybe i'm over watering? or under watering? i've read so many articles and watched countless videos, but it feels like i'm missing some secret plant whispering language. anyone else experienced this? or does anyone have any tips for a hopeless plant parent like me? also, if you have any easy plant suggestions that could survive my lack of a green thumb, i'm all ears! 🌱
