your brain is biologically wired for you to be scared of doing something that could potentially lead to you being "kicked out of the tribe",
in this case, it would be the "normal behaviour tribe".
because approaching is not "normal", people don't do it, and that's your advantage.
after you approach many girls, your brain will start seeing patterns: for example, it will realize that you're not actually being kicked out of the tribe...
people don't care about your life and who you approach, step by step, that mental thing will vanish, will get close to 0
a good thing to start is open indirect, just go to the jewellery store or fashion and ask advice to a cute girl, tell her that you're looking for jewels for your cousin... that will get you started
