You're interacting with her and 1 of 2 things happen (if not both):
1. You feel that if you demonstrate your high value qualities (DHV) and your overall awesomeness,
that you may come across as bragging. So you don't.
2. You do actually attempt to DHV, but it sounds so try hard and now you're just that guy who just brags about himself,
straight up unattractive bruh.
And what's worse is that both roads lead to the same result -
You, stuck in an interaction going nowhere slowly and her attraction for you plummeting by the second...
Learn how to Demonstrate High Value without bragging, by using
the subtle technique of dropping DHV Hooks in the interaction.
A technique that I use myself.
A technique that I teach my students that I coach.
