I myself can be quite an un-modest person when it comes to flattering ones self. But, it's really not that bad of a quality to have. It's not healthy to never compliment or flatter yourself.
If you're wearing a really nice outfit, with some nice makeup you should look in the mirror and say "well hello there, what's your name" "you look so good" "looking fab" "dayummm". If you're really good at something you should say "hell yes I'm good at this".
Sometimes when someone compliments you, saying something like "you look stunning" don't deny it, reply with "i know". Flattering yourself isn't being selfish, it isn't boasting, it's appreciating the beautiful, amazing person that you are?
