More than 90% of dating advice is overfitting. It’s high stakes and there is plenty of signal to glean, but once you know the basics of the situation the rest is up to chance. Which means if you’re being picky (and I think to should be if you can) success can take a while. In the meantime you could end up desperately pulling apart facts like a conspiracy theorist. The best advice, at least for people that aren’t super lucky, is to stop trying, do the obvious things (be healthy, happy, financially comfortable) and live a life that puts you in contact with women.
