A big component of successful gaming, and really, every area of our lives, is how in touch with the external world we are.
There is nothing physically blocking you from speaking to a hot girl, only mental obstacles make it so.
This is an easy technique that you can use to be more in contact with reality, make yourself more extroverted, and reduce the bullshit in your head.
The ability to see the world "as it is" will free you up for action.
The Extroversion Drills
The purpose of these drills is to put you in contact with the reality around you.
Drill: Put your eyes on things your walking by.
- Put your eyes on a lamp;
- notice the lamp;
- notice that you're noticing it.
This will shut down the parts of your brain that are always chattering.
Being unable to communicate with physical objects, like a chair and a lamp, makes you unable to communicate with human beings in an extroverted fashion. This is related to being in the present moment, seeing what's really there. Actually seeing something instead of just resting your eyes on it.
If you want to speed it up: Take a walk around the block when you come home from work. Do it as an active exercise. Actively seek out places with people and objects. Notice things and notice that you notice things.
If you work with people all day, the problem gets turned around. Salesmen and people in the medical field look at people as solids.
Do the same drill, but when you look at a person, look at them as an entire person. Take them in from head to toe as a person, and find 2-3 things you like about them. Try to restore the humanity/liking between two humans. Stop looking at people as objects.
Do these drills until you're absolutely sick and tired of them.
Wrapping It Up
This helps you extrovert. Notice I didn't say "become extroverted." That is a nominalization, making a process a stuck thing. Being extroverted is a process. By noticing things in your environment, and noticing that you are noticing these things, you shut down the bullshit in your head and further the process of extroversion.
Combine this with simple meditation, diaphraghmatic breathing, and simple relaxation tools and you'll be able to shut off much of the bullshit going on in your head and take more action.
