I think people have the idea that confidence is the idea that you're flawless and that you know you're the shit. This is a very high bar to live up to, and pretty much impossible since we all have emotional baggage and things we aren't proud of.

How many times do you see high status women with absolute scum bags? They like them despite their flaws. Who is to say that the same thing can't be done for you?

This is much more helpful to my confidence than trying to convince myself I'm amazing and the greatest thing to walk the earth.
