"The best investment you can make is in yourself."

解释：百姓参加了劳动就会因劳累而去思考如何节俭律己，若经常思考这些问题，就会使自己的心地善良起来；无所事事就会放肆起来，一旦放肆，就会忘掉善良，没有善良就会滋生作恶之心。

释义：解决困难问题，应从还比较易于处理的时候开始；铲除邪恶，应趁它尚在细微的时候进行。

The biggest risk is not taking any risk. In a world that's changing quickly, the only strategy that is guaranteed to fail is not taking risks.

心理学必须是实际生活的指南。
