I would say the statement is true, but there is more to the truth than what is stated.
PUA is all about respecting yourself and learning to love yourself. The result of this thinking is believing that you are a hotshot, the greatest prize for any person. Continuing down the chain of reactions, this is supposed to make you look more attractive to others because you have more confidence in yourself.
But just like beauty is in the eye of the beholder, so is value.
You could view yourself as being a million dollar man, but you could be known as the guy worth two cents to everyone else. It all comes down to how others view you, and it's something that you can influence, but you can't control.
That's why there's two sides to value: personal value and social value. Personal value is how much you view yourself as valuable. Social value, as the name implies, is how valuable you are as declared by others. Both are formulated from opinions and facts, and both can be influenced and manipulated. The only difference between the two are the judges.
"There is no better than adversity. Every defeat, every heartbreak, every loss, contains its own seed, its own lesson on how to improve your performance the next time." - Malcolm X
