Ah, the flea market. The tables, the booths, the smells, the locals…the lessons.

These markets are a microcosm of the business world, a stripped-down space where the simple rules of supply and demand are on full display — along with a ton of valuable lessons entrepreneurs can use on and offline.

Our host Omar and $100MBA co-founder Nicole recently took a trip to the Kirribilli Market in Milsons Point, in Sydney, Australia. There, they saw dozens of small business people struggling to turn their hobby into a living. Some were doing better than others, and the reasons for their success (or failure) are applicable to every industry.
