Spirit of Competition is good but not if you are in the same team. Suppose you are part of a team working for a project and you are looking to perform better than a team member or all the other team members. Now, this thing will make you notice the flaws of the other team members but overlook yours, and without knowing your flaws, you can’t perform better. It will fetch more pressure to you. It may also harm your relationship with the other team members and the performance of the team.
