教学的艺术是帮助发现的艺术。
Perhaps one day you muster the courage, to make a clean breast of everything in the heart only ended up to let others see the joke, because they did not understand you to say what, also don't know why do you think things are so important, say, almost cried out. I think the worst thing in the world, than with full of heart and secret, but no one can tell, but no one can understand!
The biggest mistake you can make is believing you know everything. Stay humble and keep learning.
