Thanks guys for all your help and support! It really means a lot.
Today AA is back like a bitch. I couldn't make a single approach even though I saw some interesting girls. The best I did today was a cute girl in a 2-set who was smiling as they walked by. Not sure if she was smiling at me, or about something else. I said "Hello" to her as the two walked by, and she greeted me back. But I wasn't warmed up at all, and also she was with a female friend. So I didn't talk to her more.
Yesterday something similar happened. I saw several single girls at the beach, but none of them I found attractive enough to want to talk to. Then when I finally came across a hot girl that I liked, I said "hello" while walking buy but in a rather soft voice, just to see if she'd be interested. She just kept staring slightly past me without reaction...
Should definitely have used a stronger opener like
@Chase suggested. It would have been smoother to walk past her slowly, stay there for a couple of seconds to get her used to my presence for a moment, then turn around and say something to her. It would have also given me time to think of something to say.
I'm not sure if your opens are usually as tentative as the ones in this outing seem.
I believe my opens get better when I am warmed up socially. One thing I realized recently, is that sometimes I don't warm up all day, either due to AA (like today) or because I just don't see any girls I want to approach (like yesterday). I work from home, so when I go out to sarge, I typically haven't interacted with too many people in person.
Then when I come across a girl I like, I'm not warmed up and can't come up with a good opener.
Another sticking point is that I will like a girl, but think she is too young for me. Just now I was at a supermarket. Saw a girl that I found interesting, she wasn't super hot or anything, slightly chubby, but I liked her style. She wore a belly free top that accentuated her large boobs and slim waist, tight jeans shorts, and had a nice womanly figure overall. Not fat, but not as thin as I usuall go for. She had patchwork tattoos over her arms that I found looked cool, and a nose piercing. But: She looked like she might be 20 or maybe even younger. I just turned 50, ha.
Also, she was wearing huge headphones which distracted me from talking to her. I always think girls wear those to keep guys from talking to them.
Probably those are limiting beliefs... Maybe I should make a point of deliberately asking some of these "too-young" girls how old they are, and find out if they even care about the age difference.
