Please read the conclusion of the sample essay “Why We Need Mistakes,” and answer the following questions. 1Since mistakes will eventually benefit us, we should not be afraid of making mistakes. 2If we treat them properly and intelligently, we will learn from them and make progress. 3John Powell, a well-known British musician, once points out, “The only real mistake is the one from which we learn nothing.” Does the quotation from John Powell in the final sentence address the same issue and then successfully wrap up the essay?
