To quote one of my favorite philosophy books God's Debris, I had to comment about how most people tell you to be yourself.
"Advice to "be yourself" in simply nonsense. If it means to do what you think you ought to do, you are already doing that. If it means that you should act as if you are not effected by societal influence, then that is the worst advice in the world because you would probably stop showering or wearing clothes. "
Just my 2 cents, I think Steve's advice was the best here. You can't simply obtain a girlfriend because you want one and you can't trick girls into becoming your girlfriend. By simply exerting boyfriend-like qualities to those you already care for will attract potential girlfriends as they witness your caring, charm, and attitude towards those you care about and wish to also be close to you.
