Yes! Yes to all of this. I am not downsizing my living space, but this year my goal is to buy only secondhand. Via thrift or vintage to minimize my footprint as a consumer. Also, I had some great success on Poshmark too and just wrote a post about it! My expectations are low, but its awesome how little effort it takes to sell stuff on there. Good luck on your journey, and I'm excited to read the rest of your blog!
