I think this is the gist of the kind of attitude the OP needs:
"Not Giving a Fuck"
If that does not work...perhaps try;
"Being Gay"
On a somewhat serious note...there's been a lot of mean-sounding advice in this thread such as "grow some balls", but in some sense this is the essence of what must happen.
If we think about this in terms of our millions of years of evolutionary history...Ugg, did not get to survive and replicate his DNA by talking to Ulga about her feelings in the Cave...In Fact, there's a good chance, if we're around today, it's a good chance our early ancestors did a fair amount of brutal raping. It would have been a key catalyst in making sure you created enough offspring to give them a chance to live and reproduce themselves.
Unfortunately, our mother's growing up teach us how to be nice and caring husbands...but mommy's not going to tell us what makes her panties moist...some of us have a harder to time breaking out of this frame.
But we have to think about it like this...women, even butt nasty women are approached and hit on by dudes all of the time...even if they put in a sincere effort to try and evaluate all of them on their internal values and needs, they wouldn't have enough time in the day....hence it's only natural to create a shield against vanilla niceness and be attracted to pea-cockish, alpha male characteristics in hopes of there being potential long-term connectivity in addition to these traits which have been ingrained as attractive at a basic level since the days our brains were little.
So, fwiw, I'll give you my two cents on some real world advice on how to improve and get to the point where women will get to the point where they can see you for the good guy that you are:
1. Go read through a romance novel or two...broads rip these things off of the shelves. I recommend a particular book called "Dangerous Men and Adventurous Women"
2. Watch some old movies when great male archetypes were still in Hollywood: Bullit with Steve McQueen, The Bond films with Sean Connery, Paul Newman, Cary Grant, Humphrey Bogart, even some of the cheesy Elvis Movies. Also, watch comedians, even self-deprecating ones; notice the way they can make fun of themselves but in a way that somehow conveys alpha male characteristics because they're getting the whole place to laugh.
3. Go to strip clubs often...all the time in fact and practice flirting with and conveying alpha male characteristics to the strippers because they HAVE to flirt with you...it's their job. Don't pay them money and don't offer them cocaine, just practice trying to give off some of these "jerk" characteristics that women by some consequence of their biology seem to go for.
Think of it as scrimmaging for the real game. IMO this works better than just trying to get better cold turkey out in the real world because the natural fear of rejection is at the very least, diminished.
That's just my two cents. Spend enough time in a strip club and soon you'll see that common denominator in all these chicks...just a little insecure teenage girl looking for the strong man to cash the promissory note Walt Disney gave them long ago.
