As Goethe says, “man errs so long as he strives”, no one can avoid making mistakes. Therefore, what we need to do is to recognize and revise our mistakes and learn from them.
For one thing, from mistakes, we learn to be more careful and observant. Small though a mistake is, it can destroy the whole plan that we are engaged in. Therefore, in the process of finding mistakes, we are also shaping our characteristics of carefulness and cautiousness and strengthen our capacity of observation. We understand that success consists of details and we could not ignore the smallest mistakes.
