Yesterday I went to a party with some friends, it was lit, there were a lot of hot girls and they were drinking and smoking. I drank a bit and smoked some weed too so I was lit. Then I approached an 8 and we started talking. I tried to keep good posture (I slouch too much) after talking a bit I literally ran out of words to say. So she left, that happened again later on that night. Honestly I'm happy with just trying yesterday as I see being rejected doesn't kill you.

So I ask your help in three things. 1. How to keep a better posture 2. How to approach better 3. And how to talk, and not run out of words.
