Looking down on pple i feel inferior to to validate my own insecurities

I noticed tho quite rare that i'll intentionally look for a flaw on sbd that intimidates me in some way (esp attractionwise) that i will look for sth 'bad' that they have to make me feel superior to them and not be insecure anymore and i'd like to know how to stop it. Though i do think that sbd can appreciate themselves and notice their own unique qualities that others might not have but doing so without looking down on others for not having them. What are your suggestions on how to stop and have a more healthy way of dealing with my insecurities
