1. What kind of girls are you going for?
A lot of times, the problem is that young cats chase girls that don't usually date their 'kind'. It could be their style, ethnicity, income-level, age, speaking patterns - the list goes on. I know that I've been guilty of this as of late.
Tighter game means your dating pool increases. A verbose cat with solid confidence can date hipsters, careerists, sorority-queens, punk-rockers, and club-girls. (Preferably all at the same time). But most young cats don't have tight game. They're just starting out, aren't very interesting, and aren't quite smart. So as a young dude, he should:
a) find what kind of girl dates his kind' - easiest way to do this is for him to look in the mirror, let go of his ego, and stereotype himself.
b) start tailoring himself more and more towards that type of girl.
2. What's wrong with you?
Herzberg would call this examining 'hygiene factors'. This isn't only about game - its also about style, grooming, personality, appearance, and a host of other factors.
A lot of new cats get into game because they don't get laid. A minority can easily get laid if they get rid of a simp mindset or tweak their game a little. The majority, however, have some issues that need to be addressed.
Here are some common ones, there are too many categories to name:
a) (Literal) Hygiene - Bad breath, yellow teeth, unkempt hair, pepperoni-acne, oily face, etc. Girls will walk around guys with hygiene issues, just to avoid them.
b) Composure - The biggest issue I see today is anxiety - most young guys are very anxious and shy around strangers. Even if a cat feels anxious, he shouldn't show it. The same applies to fear and mania - no matter how scared he is of her pet dog, or how wired his ADHD medication has him, he shouldn't let his emotions manifest themselves externally through his behavior.
c) Vibe - Somewhat related to Composure. Plenty of cats try to be either intimidating or nice. Chicks see that as 'try-hard' and 'creepy' respectively. Put out an easygoing, cool vibe when you want her to open her legs.
d) Style - Every guy needs to have his own style for an occasion. Wearing that Old-Navy T-shirt with cargo shorts and crocs isn't going to cut it. He's just another anonymous face that she saw at the strip-mall or in McDonald's.
e) Odd behaviors -
Credit goes to Roosh on this one. Don't do weird stuff - very few girls have 'sleep with mentally-handicapped guy' on their bucket-list.
f) Physique - Fat cats and skinny cats get laid the least.
The list goes on. But that's what getting laid comes down to - going after chicks that will respond positively to you and your game, and eliminating your most negative traits.
