First of all, there's no "one size fits all" approach to flirting with women in my experience. So if things aren't going well when talking with a woman, understand it might not be something you're doing wrong, you may not be compatible with them.
If I had to describe confidence, I'd say it's a quiet thing. It's not loud and brash, bragging about your accomplishments or your belongings. It's not the clothes you wear or how much you go to the gym (while these things can help you to feel more confident, they don't create confidence that's not there). Confidence is feeling comfortable with yourself, comfortable in your own skin. And here's the weird part: confidence is letting go of the desire to be with the woman, and just letting the conversation go where it goes. By not focusing on your goal, you free yourself to enjoy the moment and you will find it so much easier to have that conversation.
More than meets the eye...
This is really cool. I could see a lot of uses for this, from deliveries by drone to a bigger better Mars quadcopter rover.
