Could you do the same job every day for 72 years...?
... and still be as passionate, if not even more so, at the end as you were at the beginning. I urge you to be inspired by the story of Jiro. It's all about achieving mastery in your chosen field.
Jiro Ono is the title character of a new David Gelb documentary film, 'Jiro Dreams of Sushi'. I'll look forward to seeing the film, but you can get a flavour of this unique 80 year old multi-Michelin star Sushi master's approach from this above average LinkedIn article. Inspiring stuff for the weekend!
