Resilience is built through overcoming challenges.

A program that has not been tested does not work.

有时候，关键在于如何打好一手烂牌。

I write to find out what I think.

Today is cruel, tomorrow is crueler, and the day after tomorrow is beautiful, but most people will die tomorrow night and won't see the sun of the day after tomorrow.

复杂性不仅仅是系统中组件的数量，而是它们相互作用的性质。
