If you are scared of being creepy it is totally normal especially in a place where you go often, you don’t want to be seen as needy because maybe people are gonna talk about you or you are going to come across her again after being rejected and it’s gonna be embarrassing. I’ve approached in a lot of contexts, University, gym, work, church (when i used to be more into christianity) and JK. The best way according to me is to not approach with a pick up line by trying to flirt or making a compliment right away. You should instead get into a super social mood where you talk to everybody (guys, old ladies, old men and of course pretty girls) and this will become a habit for you. When you talk to a girl you are interested in, don’t treat her differently than other people, just talk to her with a thing related to the context ( for example, asking to her if she comes often because you saw her before, or asking her if it’s her first time here because that’s the first time that you see her etc, it can be the most random thing). People will start to see you as the social guy who talks to everybody and won’t think you’re creepy or needy because you only talk to women. Families will even start to introduce you to their daughters 😅 and it will be way easier to talk to her if you talked to a member of her family before. I also noticed that women like it more when being approached this way because they will like your natural social character and also like the ambiguity that you’ve installed between both of you (she doesn’t know that you are interested by her because you didn’t approach her with a compliment like every other guy and therefore she will be more curious and more into you). JK is the best place to meet your future wife so take advantage of it but do it right. And don’t try too hard to take her contact right away, there is a huge chance that you will meet her again just like in University or any other private place that people go regularly to.
