I’m searching for a resource to get the basic and principles?
I’ve read too much and now nothing stick to my brain and I’m all confused and I think got worse at it.
Please just give me the layout and from there I’ll just practice until I feel I need to do more.
Like some people compliment it is okay some say it isn’t.
Some tell me to be direct and some say be indirect.
Some say just do observation- like at the beach go all the way make a gesture for her to put off the headphones and tell her you seem like you have good day or it’s hot I wouldn’t be able to tan more then 10 minutes. But other people tell me it isn’t socially acceptable.
Some say just open a conversation through hi, how you doing? And then Intriguing her with my convo skills.

I want to simplify. Choose a route and just practice it without having to think to much.
