Most men are afraid to meet a girl on the street.
And this is understandable because we are afraid that they will think badly of us and all our friends and relatives will find out about this awkward approach.
If you really want to overcome fear, then approaches should become your habit and every day you should approach at least 3-5 girls and communicate, exchange numbers.
Only practice can overcome this fear. For starters, you can simply ask what time it is or how to get to the library. After you understand that this is not so scary, add compliments to the girls in addition to the already memorized phrase about the library, well, later, when this becomes a habit, ask a simple question, what are you doing tomorrow night, I would like to have dinner with you.
