I have never cold approached, only talked with girls who were already in my social circle like school, college, any activity or group etc... But today I saw the most attractive girl I've ever seen, and while I was wondering if I should do something or not she disappeared. So now I'm living with the "what if" question, and I want to start cold approaching in similar situations in the future. I guess the best way to get good at it is by practicing, but if you have any tips I would be thankful
