Nobody reflects, they just do things without thinking. Most overseas students who come back can only talk about what is new, not what is best. When you talk about what is best, you must include the old as well as the new. But most people have no ability to talk about these old things.
一般自國外留學回來做的，都是只談最新，不談最好，一談最好，就必須把舊的包括進去，但一般人沒有能力談那些舊的。
