I see what you're saying, and I'll certainly try.
Again, I'll try. It's just hard when you feel so down on yourself.
For instance, I've just recently paid for 6 months subscription to Match. Before I paid, it said 6 people had added me to their favourites, and I had views from about 10 women everyday. Of course, it says I have to pay before I can see any of these, so I paid for membership. Turns out nobody had added me to their favourites (so where the giant red '6' came from over the 'Favourite' tab, fuck knows), and all of a sudden, the profile views from women have stopped. This has only made me feel worse about myself, because I feel conned, and that it makes total sense that no women have showed interest in me on a dating website. I feel like an utter loser.
And you'd probably feel the same if you were 28 and had never been remotely intimate with a woman, or even got anywhere close to dating. I know I am not the only one in this boat, but damn, I think you have to be really unlucky to end up in this situation.
Obviouvsly you are a loser: you spent part of your life thinking of being one and talking about it.
Your perception of yourself and reality comes from what you train your brain to think: your routine-thinking is "i have low value", so this belief reflects in everything you do and in interactions with other people.
Negative thinking is like a bad habit or an addiction, you can simply stop it and start seeing yourself in a different light, there's no need to succeed in anything to start this.
Just build new and positive thinking habits by repetition (and affirmations).
Start by counting how many times a day you tell bad things about yourself in your mind and do the same for the positive ones.
The negative will clearly outwheigh the positive, no doubts here.
Invert the process, day by day, dedication is the answer: there are years of negative thoughts and limiting beliefs on your shoulders ready to be wiped away.
You can watch Brent Smith videos (the guy in the OP) or read some NLP books to go deeper, it's worth it.
Your approach to dating is also flawed: you are convinced, like lots of guys, that a woman will give meaning to your life and things will be different by default.
I've got news for you buddy: women don't give meaning to life, ONLY YOU can!
Quit the negative thinking, begin to detach from all the outcome that you think you need so badly.
If you stop obsessing about things you'll get them much easier.
And, for your previous answer: yes, women can sense lack of confidence and deep insecurities, like anybody else.
As other posters said, there's no need to be a psychic, body language and choice of words make you an open book.
The secret to project a confident aura is to think about yourself as a confident guy, no strange technique involved, no better job required.
