If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

We are all wanderers on this earth. Our hearts are full of wonder, and our souls are deep with dreams.

自由与秩序并非不相容；真理即力量；自由讨论是真理的生命。

The safety of the state is the highest law.
