There was a child who, when he was in high school, his parents chose the literary path for him. It took him only one semester. The teacher wrote the conclusion in his comment: "The student should study hard, but be too polite and rigid. Even if such a person has perfect morals, he must never make achievements in literature. "Later, after thinking that the chemistry teacher understood this characteristic of him, he suggested that he change to chemistry, because what is needed for chemistry experiments is meticulous. After studying chemistry, he seemed to have found his own stage in life, and his grades were far ahead of his classmates. Later, he won the Nobel Prize in Chemistry, his name was Otto Wallach. This story mainly tells us:. ['Parents should not choose a life path for their children too soon.', "Teachers play a decisive role in children's success.", 'Human beings have only characteristics but no advantages or disadvantages.', 'Good at taking advantage of "disadvantages" may lead to success.']
