As you grow older, you will discover that you have two hands, one for helping yourself, the other for helping others.
The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.
释义：不能因为暂时的得意就自夸能力出众；也不能因为暂时的失意就丧失自己的志向。
释义：勇敢的人敢闯天下，什么事情都能做成；过于谨慎的人却处处束手束脚，一步也难以前行。
Your brain is your most important asset; take care of it.
