Without criticism, there will be no opportunity to progress

Without criticism, there will be no opportunity to progress.
【Xian’er says so: “It is a good thing someone criticizes you. ” 】
Zhao Xiaocui often complains that Xian’er ice cream is not bright-colored.
And it doesn’t taste romantic.
And it is not cold enough.
And its shape is too dull with just one ball.
And why there is no ice crystals in it.
Furthermore, Xian’er cartoon characters are too rough in their motions.
And the story is just so so.
And the stage props are far from being real…
There was much gnashing of teeth when Xian’er asked: “Anything else?”
Xiaocui Zhao said: “And the toilet you cleaned is not as bright and shining as you claimed.” 
Xian’er tossed and turned that night.
He could not sleep and his nose bled.
Till dawn, he thought of Shifu’s book and found the following.  

 Below are quoted from my Shifu’s new book, Say Good Things—Master Xuecheng’s insight on the path to speaking like a Buddha.
It is a good thing someone criticizes you
Such that you will not become too conceited.
Without criticism, there will be no opportunity to progress. 

若无人挑剔，就没有进步的机会了

【贤二如是说：有人批评是好事】

赵小翠老是说贤二的冰激凌颜色不鲜艳，
还说冰激凌的口感不够浪漫，
还说不够冰凉，
还说造型太单一了，就一个球，
还说冰激凌里为什么没有冰碴，
还说贤二的动画片人物动作太糙，
还说贤二的故事太一般，
还说贤二的道具不够地道.....
贤二牙齿咬得咯吱咯吱地，
问：“还有什么？”
赵小翠说：“你的马桶刷得根本
不像你说的那样，如眼睛一样明亮。”
当夜，贤二辗转反侧，
睡不着，还流了鼻血。
直到天亮，想起了师父的书，
找到了这一句，才算过去了。

以下来自我师父的《好好说话》
有人批评是好事，免得太骄傲；
若无人挑剔，自己也就没有进步的机会了。
