“As humans, we have evolved to compete; it is in our genes, and we love to watch a competition.” – Peter Diamandis

If you are a coder, and you say you are one of the best coders out there, I would ask compared to whom? If you are to prove yourselves better, the primary need is to have someone who is less good than you. While you may feel that comparison simply increases restlessness; a healthy competition, can help you show your competence. This becomes necessary if you are on a lookout for a good employment opportunity as a coder. Coding competitions are a great option for this.
