How do you instill confidence in your girl as she grows up?

I saw a video on Facebook of a father making his 4 yr old stand in front of the mirror each morning and making her repeat positive phrases like..I'm beautiful no matter what anyone says I can do anything if I want to My parents love me I love myself I have a fabulous body I'm intelligent I won't listen to anyone say wrong things about me or my looks or my color or my family... God loves me There were oyher things he said but I could take in these... He made her say this each morning. So I guess repetition is the mother of all learning...instill in ur girl the basic facts tht u and her dad will be there always...tht confidence is enough for a girl
