Understand how other people think, and why they behave the way they do, without taking it personally. Communicate better.
How much time, money and energy have you wasted hitting on a girl only to be shot down? Does this happen to you over and over again? Maybe you even thought you had a great conversation going and then all of sudden it’s like someone just flipped a switch and suddenly she’s no longer interested…shot down….again… Yeah, I know… It used to happen to me too…all the time.
