I'm sure there's people out there that this is genuinely great advice for, but at least from my perspective, it just reads like an extremely long way to say almost nothing. "be out there and be confident" is like the most basic possible dating advice, ever, and is really only useful if you're completely off track on things. And to some extent, I feel like the article did itself a disservice by making it entirely gender neutral, because like it or not, society still tends to be highly gendered, and the problems people face in dating tend to be different along gendered lines.
It's like the "have you tried restarting your computer" of dating. It's the most basic possible piece of advice. To that end, most people have heard it tons of times, especially if they're in the market for dating advice. It's not bad advice, just not anything special.
Sure on individual level but without knowing the person there is not much general advice to be given. It will always be general things like don't be ugly or shy.
