Instruction does not prevent wasted time or mistakes; and mistakes themselves are often the best teachers of all.
指导不能防止浪费时间或错误;错误本身往往是最好的老师。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
A language is not just a body of vocabulary or a set of grammatical rules. Every language is an old-growth forest of the mind.
语言不仅仅是一组词汇或一套语法规则。每一种语言都是心灵的原始森林。
Go find something that you haven't done before. Don't do the same thing over and over again.
去找一些你以前没有做过的事情。不要一遍又一遍地做同样的事情。
