From Side Hustle to Passive Income – Any Success Stories?

I’ve been tinkering with a few side projects lately, mostly around digital marketing and content creation, and I’m curious if anyone here has managed to turn something like that into a steady stream of passive income. What worked for you? Did you focus on building an audience first, or was it more about creating a product or service that could run on autopilot? I’d love to hear what steps made the biggest difference in your journey. Any pitfalls to watch out for?
