Eh, advice like that is part of what puts guys in position to where they start watching shyt like this.
For most people, "Be normal, funny, and hobbies" only works if you have other stuff going for you (confident, good social skills, kinda attractive or not ugly). You might meet that 1 person that has common interests with you, occasionally, but options are limited.
It's basically the issue with modern dating advice in a nutshell. It assumes that you already have other stuff going for you, and just need a few fixes: this is because humans
in general are not good on picking up the subtle things that make up the whole. It's also why we are bad at predicting things sometimes or ignore red flags in relationships.
The reality
@Ezekiel 25:17 is that a lot of people -
especially nowadays are raised never being taught how to have sex appeal. So those who are naturally confident or sociable have a easier time naturally developing attractive traits without realizing it, while those who are
not naturally confident or sociable suffer - especially in today's sedentary, internet-heavy world that gives less opportunity for practicing socialization.
