I second Pallav's thought. It is important to have competition but with yourself. There are two more factors that are equally important: Arrogance And Self-Importance.
Arrogance works as a sweet poison. It kills your personality slowly. Once the person starts to become arrogant towards things, he/she would become more negative towards life. Negative vibes will make them take self centred decisions.There is a slender difference between self importance and being self centred. It is nice to give yourself importance, but it's terrible to think only about yourself. One must learn the art of not forgetting about other while taking decisions arrogantly.
An arrogant and self centred person believes they are always right, better, smarter, or more important than other people. No matter how impressive, talented or clever they thought they were, you probably didn’t find such people attractive.
