It’s triggered by comparison. Our incessant determination to hold ourselves up against someone else’s standard.
The problem with this is that we usually underrepresent ourselves on this crucial scale, and we tend to overrepresent the other party, leaving us to inevitably conclude that we are worse off, or for some reason… lesser.
This, in part, is because we are inherently bad at recognizing the magic within us. We tend to downplay our own superpowers, our strengths, talents, and the traits that set us apart. We do this because to us, it’s just us. We live with it. And because we live with this talent, and access it freely, we devalue it.
This is the principle of Scarcity in action. This is a fundamental principle of behavior and life that you can learn more about here, but that basically causes us to value things which are scarce over things which are abundant.
Since to us, our talents and strengths are abundant… we have constant access to them and visibility of them, and most of the time have grown up with them… we don’t really value them.
