Not true, and why "be yourself" has died as dating advice.
Do not "be yourself" unless being yourself is attractive. Even "be the best version of yourself" doesn't work if you're a brony or some other socially unacceptable group
This kind of shitty blue pill advice is why MAGA, the manosphere, etc are bigger than ever. The rise of fascism is walking on a grave of blue pills.
lol relax. I'm not saying people should never change or that they're all perfect the way they are. I'm saying the opposite: if you want to be an attractive, interesting person, and you're not that person yet, you need to spend the time and energy necessary to actually change rather than faking it. You don't have to drop your existing hobbies (e.g. being a brony is fine) but it's nice to also have a few others you can share with others (e.g. getting into running or music or something as well).
No, the real blue pill is pretending any of your culture war manosphere shit matters or wasting any time thinking about that, because every second you waste on that is a second you could've spent improving yourself.
