Here's a great example of a guy who turned his hobby into a business, and how not having enough money forced a creative decision that made the business take off.

In 1958, Pierre Koller was a Swiss 34-year-old that had grown up in Lausanne and Zurich. Fond of collecting horse carvings and old furniture, he opened an antique shop in Zurich to sell some of it off.

The following year a German clock collector offered to sell his timepiece collection to Koller—for 100,000 Swiss Francs. That was way more money than Koller had but, seeing an opportunity, he convinced the collector to agree to a consignment arrangement where Koller would auction the clocks off.

The auction is a success, and Koller Auctions is born. Today the company has offices in Zurich, Geneva, Milan, Moscow, Munich, New York and Beijing. I've been combing through their archives and found some pretty cool stuff:
