This can be looked at in a positive light. Most (many) players think they are far better than they are (especially newer'ish' ones, but also many who've been playing for years). You sound open to learning which is a plus.
Pretty much this x1000.
Virtually all poker players have, at least at some point in their poker "career" (if not always), thought they were better than they were. It has happened to us all. The fact that you recognize that you have a lot to learn means you've broken down one of the biggest barriers to actually getting better. Never stop believing that you can learn and improve, because EVERYONE can.
And I agree that you'll find this forum is one of the more friendly and accomodating to beginners, provided your questions are sincere and you take to heart what is offered to you. It doesn't mean you have to agree or adopt the advice you're given, just take it in the spirit that it's offered (someone trying to help) and move on.
Where things fall off the rails and people's feelings get hurt is when someone posts something blatantly wrong, or asks for advice, and then doesn't like it when someone comes back at them with a truth they don't want to hear. Then they get all defensive and argumentative about it. Ignore the trolls and listen to the experience available to you here, then ultimately distill that down into what works for you.
