Search Results: nice things guys want to hear

So, I have been reading and listening to the book "The subtle are of not giving a f*ck" by mason mason. And, it's very enlightening after listening to the book for a few hours, and I would recommend everyone else to give it a listen to or read, however just be prepared for the profanity language the author uses.
So, there was this part about women, gave example of guys and what ever, but mentions the guy who is whatever about everything, doesn't show he cares, or just straight up doesn't give a flying F***. And, this guy gets all of the hot girls and gets laid all the time, instead of the nice guy. I mention this because I was always hit with the nice guy comment or he's way to nice. I will always be the nice guy no matter what, but once I read and listening to this book I wanted to give this "i don't care attitude" and just see where it takes me during this pandemic stuff also I'm pretty bored from school stuff.
It's been 2 weeks since I have trying the "I don't care attitude" and it's been working, a girl who friend zoned me who I talked to here and there called me to ask me out to brunch, then a girl I matched with on tinder is willing to drive 2 hours away from me to come see me, hook up, and send me nudes whenever I want. I don't know what I'm doing, but I'm in aw with every thing and stunned,. I passed the book on to my friends and the same effect happened. My friends are really sensitive, super nice guys at hear, and caring, but got with certain girls that would give us time of day, but this little tweak really made a huge difference.

So, ladies what is up with this?
