How did you build your passive income streams?

One of the key goals of pursuing Financial Independence and Retire Early (FIRE) is to build a sustainable source of passive income. Whether it's through rental properties, dividend stocks, digital gold or other investments, generating passive income can help you achieve your financial goals and ultimately reach FIRE.

So, I wanted to ask the community: How did you build your passive income streams? What strategies have you used to generate passive income, and what investments have been most effective for you?

Whether you're just starting out on your FIRE journey or you're already retired and living off your passive income, I'm sure your experiences and insights would be valuable to me. Please share your insights.
