best way to keep houseplants alive?

I've recently become a plant parent, and let me tell you, it's been a journey. My peace lily is thriving, but the poor spider plant looks like it's auditioning for a role in a horror movie. I've heard conflicting advice about watering schedules and sunlight exposure, and honestly, I'm a bit lost. Do any of you have tried-and-true tips? How do you know when to water, and what's your go-to for pest control? Also, how do you stop yourself from buying every cute pot you see? 😂 I'd love to hear your stories or any plant fails and successes you've had. Let's help each other keep these green beauties alive!
