"I don't give a fuck what anyone thinks of me"

This is really just a recognition that:

1) It doesn't matter what people think about you, it has no actual effect. 

What other people in the club are thinking doesn't matter because it actually doesn't effect you....peoples thoughts have no physical effects....you will never even know what these people are thinking....it just doesn't matter....it has no effect.

2) It's only a big deal when it's you that's doing it.

I noticed this on bootcamp. We were doing doing some of Ozzie's crazy social pressure drills. When I was doing them it felt like a big deal....but when I was watching the other guys on bootcamp doing them it seem fine, no big deal, just very funny, but that's it. Another example...it's like if your friend walks up to a girl and gets blown out, it's not a big deal to you, you don't judge him for it, you respect him for trying....but if you think about YOU approaching and getting blown out it suddenly seem a big deal....but that's just because now it's you that's doing it....but in reality no one else thinks it's a big deal, it sometimes just seems like that when you're the one doing it.
