Existence is not its own justification.
A people without children would face a hopeless future; a country without trees would face a future with even less hope.
生存的规则永远不会改变，无论你是在沙漠还是在办公室。
The only limit to our realization of tomorrow will be our doubts of today.
I don't believe in market timing. I believe in buying good companies at good prices.
