One of the biggest issues I've seen with the "average" [non-community] guy is that he hasn't given himself permission to get pussy.
Maybe his looks are above-average, maybe his style is above-average and maybe he's actually pretty confident past the first 30 seconds, but the second he puts himself in a situation where there's chicks around- all that goes out the window.
He's waiting for something.
Maybe an IOI, maybe some sort of green light, maybe even a sign from God, "Claim that pussy!!"
Here's the deal- give yourself permission to hit on girls.
