Thanks I actually kinda felt like **** because I expected to do more but maybe I'm just being too hard on myself
Yeah... Don't beat yourself up about not being successful straight off the mark, with very little experience behind you.
Try to get into the habit of randomly speaking to people around you - anyone - men and women... all ages... the women you like, AND the women you're not interested in.
I do it all the time, and when you're used to doing it, it makes things much easier (less intimidating) when you're talking to a woman you are interested in.
If I see a woman I like the look of, I look for eye contact, and if I get it I'll say something casual about whatever's happening around.
As Rocky said - The produce in a store/etc...
I've actually picked up a woman in a store - she was looking at guitar strings with a note in her hand, seemed puzzled - I helped, and after a little back-and-forth conversation, arranged a coffee date - Back at my place on the 2nd date and we were together casually for a few months.
You don't have to be startlingly witty - just open up with something casual - if at any point she seems uninterested just go about your business, no harm done - If she does seem interested, keep it going a while. Keep it short, then try for her number, or at your age maybe link up on social media... Occasionally you might even be able to arrange a meet-up there and then.
If you're nervous, it's all about volume, and desensitisation - The more new people you speak to, the easier it'll get.
