If you're looking for a quick financial return after writing on Medium, I'd suggest considering freelance writing or exploring platforms like Upwork or Fiverr to offer your writing services. It can be a good way to start earning relatively quickly. Additionally, you might want to look into affiliate marketing or selling digital products if you have expertise in a specific niche. It's important to stay consistent and build your online presence to attract clients or customers. Good luck, and I hope things improve for your family soon.
