Economics depicts humanity as a character called rational, economic man. I'd say he has to be a man- he has no dependants.

Endurance stays with you across everything, if you do it one place, you can do it anywhere. You're able to sustain because you've already trained your brain to do that.

The miracle of capitalism is that if you have a central government trying to solve something, it will come up with one averagely optimal solution for everybody. And capitalism will come up with 10 different solutions to the same problem.

When I was 15, I rearranged the sales floor in the boutique I was working in and was the best salesperson in the store.
