  • Invest in digital real estate (like niche domains or PLR products)

Pro tip: Think of these like online real estate—some grow in value over time.


Final Thoughts: Build Once, Earn for Years

Passive income isn’t overnight. It takes upfront work—but the beauty is, once it’s built, it keeps working. In 2025, you have more tools, templates, and tech than ever before to make this real.

Start small. Pick one stream. Stack another later. Let time and consistency do the rest.
