There is a difference between "ego" and "confidence". You want the latter.
However, most new people in PUA (and generally people under 25

) confuse the 2 very easily. Confidence is when you know how good you are and dont need people to tell you or spend your time trying to get people to tell you! Ego is when really your not all the full of yourself, u just fake it so people agree with you, and tbh most people i know who actually have an ego are much much more insecure. The need outside validation from friends, family even strangers.
There are other difference aswell, and some of it depends on your culture (eg. in england admitting your very good at something is perceved as ego, even if ur the best in the world :S)
In short, lose the ego, be confident in yourself. There are two types of people in the world, those who try to change reality, which is impossibe and those that adapt to survive in it.
