Seriously Bing, do not listen to those people. Please!
If "being yourself" didn't bring you anywhere with the ladies so far, and if you think that's a problem for you, then not changing anything to yourself will not suddenly magically change the results!
The thing is not "don't try to be someone you don't want to be" but "try to be who you really want to be".
I think you should actually be willing to change not specifically regarding this particular topic, I just think if you stop changing, you're not making any progress in your life. And you should always target at being a better person.
So if you're not happy with who you are right now, DO CHANGE!
As for how to pick up girls, the internet is overfilled with advice on that so I'm sure you'll find all the info you need if you just start looking for it.
Well you can also become very rich and hire a girl, if you can cover all her expense and give her a house and whatever, you can certainly find one that'll happily suck all your money in exchange for company!
Or you can become a monk of whatever religion that forbids you to have sex or any kind of relationship with girls.
Or go to Thailand and become a girl yourself.
And remember to always only wear green underwear, girls really dig that, it's like magic! And you don't even need to show them!
