This is Yoshikazu Ono, the son of legendary sushi chef Jiro Ono. Every day, Yoshikazu rides to the Tokyo fish market to purchase the highest quality fish he can find. He employs the help of different merchants for each kind of fish he's looking for. For example, the squid comes from the best "squid guy". The tuna comes from the best tuna purchaser, etc.
In the film, Jiro Dreams of Sushi, it's the tuna merchant who explains he surveys the entire stock of fish before narrowing down his options. Then, he buys only the best one. Why? Because there can only be one "best" fish. The result speaks for itself.
You often hear people say "you're the average of the five people you spend the most time with". Are you choosing your "five" with the same care that Yoshikazu buys fish? One of the biggest challenges with really amazing companies is that they grow so large they lose their "magic". They become mediocre.
Apple (AAPL) is perhaps an outlier to this rule. They notoriously keep their critical teams very small and agile for this very reason. There can only be one "best" fish. I'm not suggesting you walk around inspecting everyone you meet like they're tuna stock. But it's important to recognize the power and simplicity in seeking the best. Happy fishing.
