Flexing on people who have less isn’t confidence. It’s asking them to feel small so you can feel big.

Displaying what you have in front of people who do not have it is only enjoyable because of the contrast. That is the whole mechanism. You are not sharing good news, you are arranging a comparison and needing them to be on the losing side of it, which requires making somebody feel small so that the feeling can exist at all. Real confidence does not need a control group.

Before posting or mentioning it, ask who is in the room and what it would feel like from their chair. Enjoy your things without needing an audience to measure against.
