唐代文学家韩愈有句名言:“行成于思,毁于随。”意思是说,做事成功是由于思考,失败则是由于随意,不经心。他把用心思考提到关系事业成败的高度来认识,是不无道理的。古往今来,许多有成就的文艺家、科学家在做学问时,都是专心致志、精思苦索到出神、入迷的例子是不少的,至今也被人们传为美谈。如北宋画家李公麟擅长画马。他画的马,形神兼备,栩栩如生。为了画好马,他曾多次到皇帝养马的“骐骥院”去仔细观察。常常是看得出神;别人同他说话,讲了很久,他一句也没有听见。他在画艺上的成就就是从善学精思来的。 Tang Dynasty writer Han Yu has a famous saying: “The line into a thinking, destroyed by.” The meaning is that success is due to thinking, failure is due to casual, careless. It is not unreasonable for him to think hard about the relationship between success and failure. Throughout the ages, many accomplished artists and scientists have been devoting themselves to their studies and made painstaking efforts to find fault with many people. So far they have also been described as beautiful talk by people. Such as the Northern Song Dynasty painter Li Gonglin good at painting horses. He painted the horse, both shape and spirit, lifelike. In order to draw a good horse, he repeatedly went to observe carefully the “Qi Ji courtyard” of the horse-raising of the emperor. Often see God; others talk to him, talked about for a long time, he did not hear a word. His accomplishments in painting are from good study.
