True wisdom is in knowing one's own ignorance.
出自北齐·颜之推《颜氏家训·文章》。书写文章要尊崇“三易”的原则，即文章内容要清晰明了，这是第一项。书写的文字要简单概要，这是第二项。书写的段落要读起来朗朗上口这是第三项。
Don't be afraid to be yourself, because everyone is unique.
The best way to help people is not to do things for them, but to help them do things for themselves.
帮助他人的最好方式不是为他们做事，而是帮助他们为自己做事。
