And gladly would learn， and gladly teach.

The music is the only thing that understands me.

The only fence against the world is a thorough knowledge of it.

Give the pupils something to do, not something to learn; and the doing is of such a nature as to demand thinking; learning naturally results.

经历一番挫折，才能增长一分见识；经过一些番磨难，才能增一分度量；省一分利益的经营，而多一分道义；能学一分退让，可得一分便宜；去掉一分享受则减少一分罪过；对事物多一分认识，而多一分物情。

The child is not a passive recipient of knowledge but an active participant in the learning process.
