Perfection

Everybody in the world wishes to be perfect, but in reality, perfection does not exist. If we strive for perfection, it is in vain. However, we should aim for progress, which, in essence, is already perfect. By making progress, we move closer to perfection.
For instance, if you want to improve your English, striving for perfection is impossible, but reading diligently every day is perfect. If you wish to become a good singer, you must practice singing every day. You may not become the best, but you will become one of the best. Writing better is the same. You have to write every day. Even if you cannot become a famous writer, you will undoubtedly write more smoothly.
However, progress is not easy; you have to be persistent every day and not give up halfway. Many people tend to switch jobs frequently, which is not good. Shallow knowledge is difficult to compete with.
