So I got this problem that I freeze when I see a hot girl in the club/bar. Sometimes I get the eye contact, but I don't approach them. And on the other hand, I dont give a fuck about getting attention of the girls I'm not really attractive to, but still, it's good to at least kiss a few of those. I don't feel motivated to just have fun with less attractive girls and escalate for a bit. I'm aware of my high standards towards women, but somehow I can't lower my standards and go for the HB7 now and then.
Anybody has/had the same and got some tips for me? Thanks in advance!

Talk to the HB7's! They might have hot friends. They are also good practice.

Your standards are your standards. You don't have to lower them. You want to get talking to the women you find attractive. This is what pick up is for.

This sounds more like approach anxiety with the HB10's and fear of rejection with the HB7's. You say you would like to kiss some of the HB7's but won't approach because of 'lack of motivation'. Maybe it is more to do with if they did reject you, it would harm your confidence and motivation further.

HB7's are approach worthy, kiss worthy, and fuck worthy in my book any day of the week, but maybe I rate girls different than most, or I have lower standards.

Clearly you have AA when it comes to 10s, we all do. I also noticed that you didn't mention 8s and 9s. What about them?

Yeah you might be right about the fear of rejection. I'm pretty confident I could get a lot of HB6 or 7s, but I just somehow I dont give myself a reason to go for it. I make excuses and I don't how to get rid of this.
8s and 9s is the same as 10s I guess. I just have to put my fears aside!

I would say majority of us rate women very similarly. I will go for HB7's any day myself as well.
I totally know what this feels like. It is a form of approach anxiety but it's not like when you see a stunning HB9/10. In that situation, you get the motivation but your nerves and adrenaline kick in!

But sometimes when you see a load of HB6/7's you may be in the wrong frame of mind and this has an impact on your motivation and the more HB6/7's you see without approaching, the more it hits your confidence.

Focus on the HB8's and you will be fine haha. You will have the motivation and confidence!
