How bad is narcissism? And am I?

Everything I am about to say may seem off topic and useless. Also like a boasting look at me thing. It's actually driven for another purpose. to distinguish if I am just extremely confident because I'm good at everything I do and not narcissist because I lack many of the traits. Furthermore, if I am still narcissistic is it a bad trait and should I try to get help?

Ok just pretend everything I say is true, and give me an answer based on what I say. If I'm lying then the answers won't help me.

Ok, I believe I'm a narcissist. I have way too many similarities in my personality to not be I think.

Brains

Now, I am extremely smart. I'm not saying that. I am quick witted and a fast learner. I've always been. I've skipped grades, and I'm the one people turn to when they have a question. I don't act like I am. And to be honest, some people think I'm dumb because I joke around a lot. Contrary to narcissism that doesn't bother me.

Athleticism,

I'm an athlete. I can pitch a baseball at 98mph. Faster than most pros. I have extremely good accuracy, and I haven't trained in the sport since I was 12. Top on the team in football, I switch from FB, DT, LB and Quarterback on my team. And always used in the game. This is my first season of football in my life. And I'm 24.

Basketball, I've schooled the top in my school in 1 on 1 and did very well in full court. I recently beat the local swimming freestyle 50m swimmer in a sprint race. I also challenged a guy who is supposedly ranked one of the top in the world in Racquetball. My first loss 18-16. I have only played the sport a few months and usually post workout and not seriously just to loosen up after the gym.

I bench somewhere around 450lbs, squat in the vicinity of 600 and I worked out 3 years in high school , and 1 year after, took 3 years off and I started lifting 8 months ago and now have those stats. For the amount of time that's very good. Now, that is why I am so confident in sports, and feel it might not be narcissism. Because I am actually decent so why should I be timid.

Contrary to narcissism again, I love I mean love finding people better than me. And it becomes my primary goal to beat them. When I don't have someone I get bored and quit. So I don't mind losing, and I have no problem admitting defeat.

Similarities, I'm extremely outspoken and aggressive(not mean) to get my point across. I feel I think differently than most people. I was always told that was because of my literal thinking. I always like to be the leader and decision maker, but I don't mind subjective debates. My main similarity is that I feel I want to always control a persons thoughts I think this is more of a game than anything.

For my main differences. I am over sensitive to others. I hate hurting peoples feelings, or watching someone feel out of place or nervous. And I'm not envious of anyone really. If someone is smart and earned his position I like to know how and why he accomplished it. But, no real idolism. Also the trait of craving attention. I like attention from like a sideline or someone saying congrats one time to acknowledge the fact they are showing respect or interest. But, more than that, when it's a constant admiration. I'd rather not deal with it.

Now is this over confidence, confidence, arrogance, or am I just a narcissist.

Also is there any benefits or are all of the traits bad and need some sort of help or regulation. I'd like to know because I never knew about this personality disorder until this last week and it seems to make me uncomfortable when I learn about it thinking.. Is this guy me? lol. Thanks and any help is appreciated. Please if you feel like calling an estat war just don't waste your time.
