I agree with Jaz. This is wrong.
The whole practice argument is wrong also e.g. like this or if people practice dates etc with girls they're not really into just to hone their
PUA skills. Firstly, it is a bit mean. Secondly, it is not even the same as the real situation as you have nothing on the line! The anxious feelings you have to deal with, with a fit girl won't be there so it's not even a practice at all. You just get good at charming birds you don't really want to pull. Great, real good skill that!
This is how I'm feeling at the moment. I may have gone quite far in the other direction recently, but that's because I'm intent on consistently pulling girls that make me go weak at the knees this year and settle for nothing less.
