“Fit” is not a new idea, but I rather like this new-to-me analogy for it:

In a fancy restaurant, the difference between any old waitress and the best may be worth a thousand dollars a night in happy customers who’ll not only tip well, but recommend the place, and return often.

On the other hand, the kind of perceptive human who can do all those things consistently, who happens to work at a 7-11 — well, there’s a limit to how much value such a food server can add there. If you’re very attentive and customer-service oriented in that setting, how many extra slurpees can you really sell? I’m thinking it would be tough to realize the same kind of value, owing to the setting.
