This is the same thing that everyone in this community keeps telling each other to help with their AA.
Most of the time we just read this kind of thing take it on board but when the time comes to approach the hot girl then it all goes out of the window and the argument in our head starts.
Sometimes it just needs that epiphany or revelation for all of the previous ramblings to become a realisation and for you to suddenly get it!
Well done for achieving this and hope that this stays with you.

Until that time of realisation, it is just continued approach after approach after approach until those nasty little voices disappear or you are able to block them out and find yourself doing the approach before you've even started to think!
