RaphaelAdroitEsq, To a certain extent I agree with you. My 600 lb man could indeed choose to lose weight to improve his physical appearance. But what if this same man is just naturally ugly? His facial features just do not add up...for whatever reason, he is just physically ugly. Short of undergoing extensive and expensive wholescale facial reconstructive surgery (which he probably doesn't have the money for) there is nothing he can do about this. So it really isn't always about "simply choosing not to suck." Have you ever heard the phrase, "you can't polish a turd."? Personally, part of the reason why I realize that I am physically unattractive is my race. But I don't know of any surgeries that can alter that in an effective manner.
And to that, I would say this........
You'd be amazed at what confidence can do. Some of the guys I know that are the most successful with the most beautiful women are some of the ugliest trolls I've met. But they've got confidence out the ass.
I could show you pictures of some guys I know in real life who are extremely successful with very beautiful women. And your first thought would be, "No, seriously. Where's the chick magnet?"
I'm not talking less than average. Some of these guys are downright ugly. And they're amazing at what they do. But they have two things in spades that trump any deficiency in their looks department; confidence and charisma.
