What are your tips for living a zero waste lifestyle?

I've been trying to reduce my waste and embrace a zero waste lifestyle, but I’m not sure where to start. It feels overwhelming, especially with all the different products and methods out there. I've swapped out a few items, like using reusable bags and stainless steel straws, but I still feel like I’m missing something big. What do you all do to cut down on waste? Are there any simple swaps or routines that you've found really helpful? And how about dealing with food waste? I can’t seem to keep my produce from going bad! Would love to hear your experiences and any advice you can share!
