Funny you used the word starstruck. I made that same parallel in my head awhile back that helped put things in perspective for me in dealing with women.
I've spent many, many years going to see all kinds of different bands, and as a result, I've met countless rock stars and other celebrities of all levels of fame from the obscure underground types like Enslaved to big name superstars like Aerosmith and Melissa Joan Hart. And I've noticed a recurring theme particularly with the megastars. If you kiss their ass and shower them with compliments, they generally get annoyed and are very short with you. But if you just talk to them like they're everybody else, they'll be a lot more friendly with you in return.
When you think about it, celebrities and attractive women are in the same boat; they both have high status that gets them an absurd amount of praise on a daily basis. This was flattering when they first gained it, but after years of having it, it has become very annoying. They find it refreshing now when somebody just treats them like a person.
After years of interacting with these people, I've become very desensitized to their "star power." In fact, sometimes I'm actually bored talking to them.
That's the key. That scared feeling is generated by the notion that this is a scarce opportunity. Interacting with someone with such high value. But if you do it enough, that feeling really does go away. Eventually, those interactions are all very casual and second nature and rather than kissing their ass for an autograph, you're asking them to put you on the guest list (which many of them are happy to do if you ask the right way).
Equate that to asking an HB10 out. It's the same basic concept.
And it's actually easier with women because hot women are everywhere. They're much more accessible than celebrities who sometimes you have to go through a lot of crap to even get to.
Just force yourself to interact with as many hot women as you can on a regular basis. If you crash and burn and she gives you that, "you're a loser," look, laugh it off and move on to the next one. The more you do this, the easier it will get. And eventually, it will be no big deal.
I'm still working on this with women, but I figure if I conquered celebrities, this should be a piece of cake if I just use the same approach.
