判断
The key to power is the ability to judge who is best to serve your purposes, and then to win them over to your side.
A miner's greatest tool isn't their equipment - it's their judgment.
You have to be willing to make mistakes regularly; there is nothing wrong with it. Michael taught me about making your best judgment, being wrong, making your next best judgment, being wrong, making your third best judgment, and then doubling your money.
