Listen to her blather all night? Some of these seem to be tips to get a quick lay, but would you want to spend your time with someone who spends their life talking about themselves? That's the antithesis of a good partner. And forget all that "nice guys finish last" BS. Nice guys are nice guys, and everyone likes nice people. I think what people mean, though, is shy, self-conscious guys can ruin their chances by not allowing their personality to come through. That personality can, and should, be as nice as pie. It's that it comes through that matters.
