"Most guys immediately destroy any chance they have of coming across as Mr. Right by broadcasting signals of weak self-esteem, helplessness, nervousness, insecurity and immaturity. They’re too quiet. They avoid eye contact. They get tongue-tied. They’re not funny or engaging. All of which scream to a woman: “Hi, I have zero confidence in myself, which means I’ve failed to meet my own emotional needs, which means I can’t possibly meet yours, either. So, for your own good, please reject me ASAP."
This advice implies that naturally quiet or introverted men must be outgoing or try to impress women in order to have confidence. These behaviors are related to personality and have nothing to do with how confident one is in their own abilities or in who they are.

The advice is great.
Being introverted and being shy are different. An introverted man enjoys small groups or his own company. Being quiet is also different.
Shyness is a lack of confidence in social situations, and it is NOT a fundamental part of who you are. It is something you can overcome to the point that you can be comfortable speaking or not speaking as much as you desire.
You are correct that a lack of confidence in social situations does not necessarily correlate to a lack of confidence in, lets say, your career or academics.
But women do want a guy who is confident in talking to them, and confident in being sexual.
As you say 'real confidence comes from knowing who you are, and what you want in life and going for it'. So go for it.1
