There are some people who are perfectionist by nature, they are often very successful and used to it. However, some other folks are perfectionist after some failure in their lives. For instance, working all day long and then going to the university, and in all free time they keep hitting the books. Making themselves productive every time without giving at least a minute. This seems good, after all, not being set in our ways means more improvement which can push us over the edge. However, if we indulge in a situation which runs out of control, keeping studying all the time would obviously harm us. We might come down with stress, hair loss, anxiety etc. So, being such a hard worker might not be so good, after all, what's the use of being so tough on yourself and then get sick with a working or studying vicious disorder ? We all need good timing some times, otherwise, the life might use its sense.
