没有完美的知识可以称为我们与生俱来的；唯有从经验中获得的知识才是真正的知识。
There is no perfect knowledge which can be entitled ours, that is innate; none but what has been obtained from experience.
Success is not measured by profits alone, but by the positive impact we leave on society.
People don't buy what you do; they buy why you do it.
"The truth is rarely pure and never simple."
We do not observe the mind; the mind observes the world through us.
