OK I'm pretty much pissed off . . .

Yesterday I wen't to a rock concert which had well over 5000 people, everyone my age and basically all the noticeable social groups in my city . . .

WELL, THEN I started approaching and nothing - WTF. Each time I approach I'd try the same approach a couple of times and then I'd ajust it . . .

By the end I had approached 29 girls and gotten 29 rejections - WTF!!

I'm pissed because rock concerts / bars / clubs are MY pick-up places, it's what I'm good at . . .

****, roll with the punches. MAN, it's the physical. I've got my personally set, but it's the physical. Which is why I'm gonna start bulking.

You didn't provide a lot of information here.

Give us examples of things you said
Do you have a photo of yourself?

There are nights, when nothing goes as planned. Just get used to it.

And juding from your post, you were a bit drunk when writing it

Don't get discouraged. It just sounds like you are trying too hard and possibly coming off a little needy. It's good to force yourself to do approaches, but remember to get into the right state of mind when you do it. You are obviously self-conscious about your body, so work on that. Exercise boosts your testosterone and confidence levels.

Try doing approaches after a nice, hard workout. You will be surprised how easy everything goes when you got a nice testosterone boost. Plus you just finished overcoming personal challenges, which is a great place from which to execute your game. (Just be sure to shower first!)

PS - Drinking can hurt your game. (unless it is tequila, used in moderation of course)
