Warren Buffet on Possession?

I'm amazed at people who recognize getting out-shot every night is bad, but place no value on seeing which players get out-shot every night.

It is extraordinary to me that the idea of being outshot every night takes immediately with people or it doesn’t take at all. It’s like an inoculation. If it doesn’t grab a person right away, I find that you can talk to him for years and show him records, and it doesn’t make any difference. They just don’t seem able to grasp the concept, simple as it is.
A fellow like George Ays, who had no formal education in hockey, understands immediately the shot approach to hockey and he’s applying it 5 minutes later.
I’ve never seen anyone who became a gradual convert over a ten-year period to this approach. It doesn’t seem to be a matter of I.Q. or academic training. It’s instant recognition, or it’s nothing.

That's not quite the actual quote by Warren Buffet, the original quote was about value investing:

It is extraordinary to me that the idea of buying dollar bills for 40 cents takes immediately with people or it doesn’t take at all. It’s like an inoculation. If it doesn’t grab a person right away, I find that you can talk to him for years and show him records, and it doesn’t make any difference. They just don’t seem able to grasp the concept, simple as it is.
A fellow like Rick Guerin, who had no formal education in business, understands immediately the value approach to investing and he’s applying it 5 minutes later.

If the Oracle of Omaha can be taken aback by the failure of the masses to accept simple concepts, Jonathan is in good company.
