I have a buddy who I hadn't seen in years. We lived next to each other in the dorms. He was your typical BETA male; shy, soft spoken, indecisive, waited to be lead. Then I saw him recently and he had gone through what we call a 'transformation.' He was an ALPHA when I saw him last. (He played in a band, so it could have been social conditioning that changed him/ gave him confidence.)
The #1 thing I noticed right off that bat from this kid which changed was, he knew what the fuck he wanted, and wasn't afraid to get it. That's what I think makes an ALPHA an ALPHA.
Here is it-----> Your personal level of perceived ENTITLEMENT.
You want it? Go fucking get it! No one likes dependent ass bitches.

Be a self thinker.
