I despise bad dating advice, as someone who works in the dating industry I find it almost insulting.

This whole "women are attracted to confidence" bullshit is getting old, very old. When women say they are attracted to confidence, do you know what they are really saying?
"We are attracted to good looking, tall men who have the confidence to approach us after we have given them the green light to do so". Telling an ugly guy to just be "confident" is like putting lipstick on a pig.
