people with confidence don't say "im ugly, i cant get chicks" and they dont make constant threads on a forum looking for attention and feeling sorry for themselves. fail
People with your sense of confidence are hubris. Not confident.
People who think they can overcome any odds no matter how fucking unlikely it is are overly cocky, not confident.
Thinking you can score any chick is not confidence. Thinking you can score X girls in relation to your Y situation(looks, personality, finances, power) is perfect confidence when done correctly.
Wiki:
Confidence is generally described as a state of being certain either that a hypothesis or prediction is correct or that a chosen course of action is the best or most effective. Self-confidence is having confidence in oneself. Arrogance or hubris in this comparison, is having unmerited confidence—believing something or someone is capable or correct when they are not. Overconfidence or presumptuousness is excessive belief in someone (or something) succeeding, without any regard for failure
