To piggy back off of the @DaygoTaco post, I did two approaches today. the first one was awkward but I swagged out on the second one. First girl was black, second asian. some personal notes
The first approach was terrible. but I really went in with some recycled garbage, and it hurt me. I could tell it was really awkward, and it was a shame I messed it up because she was fine. I really had no choice with the second one, considering she was eyeraping me. It was easier this time because I freestyled basically. She's actually a little older(27).
-Listening is the most important thing when approaching
-don't allow your conversation to sound scripted, nor should it sound like an interview. Allow it to feel organic, and show real interest in her
-Make your decision whether or not to approach in the first 5 seconds. after a while of waiting you risk other factors screwing up your game(her leaving, a friend meeting her etc.)
-Don't have a prepackaged line when you approach, look at her, then comment on something such as her outfit, her mood, etc.
-We really have nothing to lose brehs

Worst she can say is no, and it actually feels kind of good tbh. it's better to just do it then to regret it later.
One more thing brehs,
make sure you're getting some sort of exercise every day. It will help you with your confidence
