but it's what i want

Should you ever fight for something you want? I am not talking about fighting for world peace or loving others. I'll be frank with what I am talking about. Guys and Friends. I like a guy but many other girls like him and I actually like all the girls that like him. Do I fight for it or not? If anything did happen then is it selfish? Then I have what I want, but the other girls are left to linger. I am taking time away from MY friends that need me, that need my encouragement and time.
