Do you believe in "Confident Persistence" when dating women?

Anonymous
Recently this girl I had been seeing went from really hot to cold on me, seemingly out of the blue. I've been reading online for advice on what to do, and came across articles like this

that suggest continuing to pursue, but doing so in a laid-back non pushy/confident manner.

I'm wondering what people think of this concept of "confident persistence,"

Guys, do you think it works, has it worked for you?

Girls, do you think it works, has it worked on you?

Obviously all situations have their own nuances so I realize it isn't a 100% of the time thing, I just felt in my situation she had shown some interest, and maybe just hit a dip, and it wasn't worth giving up completely.
