There an old saying about "never believe your own lies".
Insecure types don't learn that, until it is too late. They truly believe in their own lies, given time and enough ass-kissing from other insecure types (their "fanbase").
A simple thing that could help someone avoid that is simply look out for WHO is praising you. If the ones praising you are awkward, anti-social, insecure and ugly freaks, that is a big enough red flag for you to know that you are doing everything wrong.
Great people, real people, get praised by other great and real people. Not by a bunch of freaks with mental and social problems, that can only congregate in confined hugboxes called "conventions", literally being put in containment places, away from better people.
If any of those on channel autism had a little bit of self-awareness, they would stop doing whatever they did as soon as they saw the very first bunch of "fans" that they had.
Always move away from losers, from the awkward, from the clumsy and from the unsocial. Being praised by them is a badge of shame. Not of accomplishment. Even worse: believing in that their praise ir worth anything poisons your mind, to the point that you become a Spoony, or a Nostalgia Critic, or any else of those demented freaks.
That goes double for women.
Being awkward is forever a shitty thing. They must aim to move away from their own awkwardness completely. Not embrace it.
But again, they are the types who believe their own lies. They tell themselves that they are "doing great", simply bickers someone else said it. Ignoring that those who said it are a bunch of freaks who should be avoided at all costs.
