This one's a bit more abstract, but still important, I think. Start keeping a file or folder – whether digital or physical – that contains all the compliments you receive from friends, family, and even strangers. It's so easy to forget the nice things people say about you, because they're often outweighed by negative comments that stick in your head more easily.
If you're having trouble coming up with material for this "compliment bank," ask 10 of your closest pals what they think your 3 best qualities are.
Help me out?
