This Teacher Sells Digital Downloads for $10. Her Side Hustle Now Makes Six Figures a Month: 'It Seems Too Good to Be True, But It's Not.' When one middle school teacher needed to make some extra income, she started a remote side hustle with no physical products and incredibly low overhead. Now she brings in six figures each month, and offers courses teaching others how to do the same.

There are very few things you can create once and then sell thousands of times over. Most businesses aren't a fish and loaves situation. But then, Lisa Fink is an evangelist of sorts. Only she's not promising miracles.

Six years after starting a fully remote side hustle — one she was dubious would make even a few hundred dollars — she's made a million in revenue, and retired 20 years early from teaching middle school.

Now, Fink teaches courses showing people how to follow in her footsteps. "I want others to feel the relief I felt when passive income began rolling in," she says. "There's absolutely enough room for everyone." Here, she shares her key insights.
