世界充满了故事，但所有的故事都是一个。

At a restaurant do you order what you know is great， or do you try something new？ Do you make what you know will sell or try something new？ Do you keep dating new folks or try to commit to someone you already met？ The optimal balance for exploring new things vs exploiting them once found is: 1/3. Spend 1/3 of your time on exploring and 2/3 time on deepening. It is harder to devote time to exploring as you age because it seems unproductive， but aim for 1/3.

切勿盲从任何权威，因为总会发现相反的权威。

出自汉·桓宽《盐铁论·未通》。修筑城墙的人，首先要加厚城墙的地基，然后再把城墙垒高；善于养民的人，首先要巩固人民的产业，然后才能使他们走向富裕。要使人民实现富裕，首先要使人民有稳定的工作。国家应该合理地配置土地资源，使农民有地可耕；还应该整治社会治安，稳定市场秩序，沟通贸易渠道，使商人有买卖可做。只有做好了这些基本工作，人民才能逐渐走向富裕。

Leadership means making tough decisions today that will benefit everyone tomorrow.

The only thing that is constant is change.
