Goethe said, if people want to pursue something, they have to make mistakes. Of course, this does not mean that you should not try to prevent and reduce mistakes, or that you can take a nonchalant attitude towards mistakes, but that you should not be timid and timid because you are afraid of mistakes. We are also afraid of this and that, and we will not be able to achieve a career.
The main argument supported in this paragraph is that if one wants to succeed in a career, he will always make mistakes.
