我开始相信，一位伟大的教师是一位伟大的艺术家，而且像其他伟大的艺术家一样稀少。教学甚至可能是最伟大的艺术，因为媒介是人的思想和精神。

成功是一段旅程，而不是终点。

The time which we have at our disposal every day is elastic; the passions that we feel expand it, those that we inspire contract it; and habit fills up what remains.

Every language is a temple in which the soul of those who speak it is enshrined.
