井蛙不可以语于海者，拘于虚也；夏虫不可以语于冰者，笃于时也。
不可以同井底的青蛙谈论大海的辽阔，因为有空间的拘束；不可以同夏天的小虫谈论冰冻的寒冷，因为有时节的局限。
Sometimes it's the people no one imagines anything of who do the things that no one can imagine.
心理学的真理是帮助我们驾驭现实的东西。
Fear is the main source of superstition， and one of the main sources of cruelty. To conquer fear is the beginning of wisdom， in the pursuit of truth as in the endeavour after a worthy manner of life.
别让恐惧决定你的未来。
