Must one experience a lot before coming to realize what he truly wants?
Xian'er says so: How am I wrong?
Xian’er asked Shifu,
Why is it that having scrubbed so many toilet bowls I still don’t have much wisdom?
Shifu answered,
It is because you have not done much thinking.
So Xian’er stopped scrubbing toilet bowls for a long time.
Shifu found Xian’er and asked,
The toilet bowls are filthy. Why haven’t you done any cleaning?
Xian’er replied，
It is because I am doing my thinking.
Shifu said: Why are you being so dogmatic?
Xian’er said,
I am sorry that I am wrong.
But Shifu, how am I wrong this time?
Below are quoted from my Shifu’s new book, Say Good Things—Master Xuecheng’s insight on the path to speaking like a Buddha. 
Thinking and experiencing cannot be separated.
One must learn to think after some experience.
It is as the old saying goes,
“A fall in pit, a gain in wisdom.”
But thinking is not necessarily limited to one’s own experience.
Those who are good at thinking gain insights from listening and/or observing the external situations.

是否要经历很多后，才知道自己想要的是什么？
贤二如是说：我错到哪里了
贤二问师父，为什么我刷了这么多的马桶，
还没有长智慧。
师父说，那是因为你没有思考。
贤二就很久没有刷马桶。
师父找他，问，马桶那么脏，
为什么没有去刷？
贤二说，那是因为我去思考了。
师父说，你怎么这么教条呢？
贤二说，我错了，我改。
可是，师父，这次我错在哪里了呢？
以下来自我师父的《好好说话》
思考离不开经历，
经历后也要学会思考，
正如俗话常说的“吃一堑，长一智。”
但思考也不仅限于自身的经历，
善于思考的人，
可以通过听闻或观察外在的环境而得到启发。
