When Mr. Liang Shiqiu, a master of literature, was still alive, he ate at the same table with him one day. When cold dishes were served, Mr. Liang said that he was diabetic and could not eat sweet smoked fish. When the "rock sugar elbow" was served, he said that he could not touch it because there was rock sugar in it; "Assorted fried rice" was served, but he still said he couldn't eat it because starch would be converted into sugar.

Finally, I served the "eight-treasure rice". I guess he won't touch it because "there is both sugar and rice in it." Unexpectedly, Mr. Liang smiled: "I'll take this." He said with a smile, because I know that there is my favorite "eight-treasure rice", so I am particularly temperate in front. "My blood sugar is high, and I must avoid eating, so I must plan to leave that' quota' to my favorite."

More than 30 years have passed, but I often think of Mr. Liang's words. I have found that many great men have made outstanding achievements because they have restrained themselves and focused on specific things.
