Great documentary on Netflix called "Jiro Dreams of Sushi."
Lots of lessons for sports parents on what it takes to achieve success. Jiro runs a simple 10-seat sushi shop in a Tokyo subway station and all he serves...is sushi. Nothing else.
A 3-star Michelin rated restaurant, with a global waiting list running months out in advance for a seat, 85-year old Jiro is still learning and perfecting his craft.
