We all know, how harmful is the habit of comparison; however, most us do compare our
achievements and
failures with that of others -- both in personal as well as professional life. Can't we look within, instead of looking at others, and be contented with whatever we are?
Well, I believe, this urge of comparing ourselves with others is in-built and it may be difficult to completely get rid of it.
However, as
Thomas has rightly pointed out: when it becomes an addiction, I mean comparing every life developments with that of people within your area of influence, it would surely invite a lot of unhappiness - as, many a times, those people with whom you compare are likely to be more successful in life.
So if you are unable to get rid of this habit, do compare but constructively and put in your best efforts to achieve more
success in life; however, at the same time, be ready to accept failure also -- and gracefully.
