This made a lot of sense to me, thought I'd share
It relates to confidence and comfort levels, in the context of trying to 'PUMP YOURSELF UP' to go talk to a girl/get a phone number/get your dick wet.
If you woke up and were going to eat cereal in the morning, you would most likely just wake up and eat it without thinking about it. You wouldn't try and pump your confidence up by saying things like 'Yeah! I've totally got this! I'm the cereal MASTER!" this would be ridiculous; you know that you can easily eat the cereal, so there's no need to pump yourself up.
We only really think positive thoughts and psyche ourselves up for something that is hard for us to do. For things that come easily to us, we do them automatically and without thinking about them.
Although it is counter-intuitive, during dates/sets/sex, thinking thoughts like 'I'm a pimp' or 'I can get any girl I want, no problem' only reinforces in your mind that the task at hand is hard for you. During interactions, don't aim for a head full of positive thoughts.
Aim for IMMERSION, the absence of thoughts
