我们都是自己的监狱，自己的狱卒。

In the face of challenges, we must remain resilient and innovative.

I don't care if you're black, white, straight, bisexual, gay, lesbian, short, tall, fat, skinny, rich or poor. If you're nice to me, I'll be nice to you. Simple as that.

每个个体改善自身状况的自然努力，当在自由和安全的情况下得以发挥时，是如此强大，以至于它不仅能够独自，不受任何协助，推动社会走向富裕和繁荣，而且能够克服往往由愚蠢的人类法律造成的百般妨碍。

行为由驱力和习惯强度的相互作用决定。

And gladly would learn， and gladly teach.

记忆就像一条永不停息的河流。
