I hear from so many single people, “There aren’t any good guys (or girls) out there! They’re all liars, cheaters, unattractive, etc.” This Scarcity Mindset can set you up for accepting less than what you want.
For example, a girl meets a guy she is interested in. She thinks he’s attractive, they get along, and she’s really excited about him. Soon she can’t stop thinking about him. She starts to picture how life would be with him. She will go out of her way to be available when he wants to see her, she wonders when she will see him again, and gets anxious when he is out of touch. Pretty soon, this guy realizes that he doesn’t have to do too much to still be able to see her and get the validation he wants. He unconsciously loses respect for her and invests less in the relationship. In turn, the girl invests more energy, wanting to keep the relationship alive.
To make matters worse, she may also have an Urgency Mindset (“I’m running out of time to find someone!”). The combination of scarcity and urgency will make someone accept even less than what they want in a partner.
In this scenario, if the girl had an Abundance Mindset (“There are millions of amazing and available men out there”) she would be way less likely to invest her energy in someone who isn’t investing back into her. She would simply move on to the next person and be closer to finding someone who will invest back in her.
