I feel special if I hear my enemy says I'm ranked #1.
Why do you feel special when people say that?
I think they are jealous of my current success.
While competition is healthy specially in the workplace, I do not think that you should consider your competition as enemies as they can lead to hostile and unfriendly situation in the workplace. I recommend that friendly banters and friendly fun competition is as far as it can go when it comes to your coworkers, so that nobody's feelings get hurt or worse, physically hurt.
I don't care, that's what makes me special!
Have you thought about how your coworkers feel when you treat them like the enemy? Don't you want them to have fond feelings towards you? Maybe try keeping your competitive spirit contained and remain friendly with your coworkers instead.
