I don't know if you would enjoy it, but keying off the idea of lifetime crafstmanship is the documentary film Jiro Dreams of Sushi[1], he was 85 at the time and ran a small but world famous sushi restaurant - no chain of stores, no growth at all costs, instead pursuit of excellence.

Quotes:

> Jiro Ono: Once you decide on your occupation... you must immerse yourself in your work. You have to fall in love with your work. Never complain about your job. You must dedicate your life to mastering your skill. That's the secret of success... and is the key to being regarded honorably.

and

> Jiro Ono: I do the same thing over and over, improving bit by bit. There is always a yearning to achieve more. I'll continue to climb, trying to reach the top, but no one knows where the top is.
