Most helpful info. Thank you. So how does "I like your___ tell me about your____sound?"
That is a good start, but there is a wealth of information to learn. It took me several years to get great at it. There are countless threads in here, and videos on youtube talking about "day-game" and "cold approach". Plenty of them are bad, some of them are great, and all of them (good or bad) have at least some haters here on this forum. I would start your research and form your own opinion on who's suggestions seem like they would work.
I will give you an example of a direct opener and an indirect opener situation I've had.
Direct: Saw a girl in Target and she was just my type. Slender, long legs, blond, very cute. She was using the self-checkout so wasn't a great place to stop her and have a conversation so I waited outside the front door for her and when she came out, I stepped in front of her while she was a couple yards away and said, "Excuse me, I know it's a little odd to approach a stranger, but you caught my eye in there and I just wanted to meet you." She blushed and said, "Oh, ok" and stopped to have a conversation. I said, "So what are you buying all this stuff for?" She explained and that opened up 100 other things I could dig into. The goal is to be a mile deep and an inch wide - don't just ask a bunch of questions and accept her first answer each time, moving on to a different topic after each question. IE she says she likes photography. Make her tell you why she likes it. Go deep into it. How does it make her feel, when did she know she liked it, etc. Then relate what she says to something you have experienced (it could be the same hobby as hers or it could be something different, but gave you the same emotion she said photography gave to her). After a few minutes, you say, "Well listen, I have to get going but we should get together soon." Don't ask - tell. But even though you aren't technically asking, she still basically has to say yes or no and if it's yes, ask her for her number and then reach out in a couple days to set the date for a specific time and place.
Indirect: Saw a really young (23 looked 18) girl at the grocery store wearing yoga pants and just my type. We ended up looking at the organic nut-butters at the same time and I said, "It's always hard to find one that doesn't have sugar added to it" and she said yeah and made some comment about nut butters and then I asked her what she was going to make with it and then that lead to other topics. Said we should hang out same as in my Direct opener example above and she said yes.
When being direct, women know what you mean when you say, "you caught my eye", but in some cases I have also said things like, "Hey, I noticed you from the park bench and you look so damn stunning in that dress that I just had to come and find out who you are". When cold approaching, I find most women actually respond better to direct approaches. This is because if you are indirect, they don't know what you want - there is a LOT of pressure there for a woman (who are smaller and more vulnerable). Is he going to ask me for money? Is he a meth-head? Is he a weirdo? Is he going to ask me to sell Amway? WHAT DOES HE WANT?!?! Sometimes a girl who might be interested may just be so nervous by the pressure of not knowing exactly why you are talking to her that she may come off as disinterested even if she isn't. When you put it right out on the table directly, you can see most of them breathe a sigh of relief and immediately feel comfortable.
Be careful with Rollo. I agree with most of what he says but it can make you black-pill, and some of it is a bit too black and white for me.
