Mike H., a janitor from Ohio, lived paycheck to paycheck, mopping floors at a local car dealership. But behind that mop was a mind full of quiet ambition. One evening, he noticed how many unsold cars were sitting on the lot and asked a simple question: “What if I helped move these online?”

With no money to invest, Mike used his old laptop and created listings on social media and forums. By month three, he was getting commissions. By month seven, he launched a micro-agency to help dealerships nationwide.

Eleven months later, he had earned his first million. All from a mop bucket and a question no one thought to ask.

Now, he teaches others how to spot opportunities in their own workplaces—and how to take action before someone else does.
