I don't think of them as teenage songs. The things that happen to you in high school are the same things that happen your entire life. You can fall in love at 60; you can get rejected at 80. ↗
I think every girl needs to love herself, regardless of anything. Like if you're having a bad day, if you don't like your hair, if you don't have the best family situation, whatever, you have to love yourself and you can't do anything until you love yourself first. ↗
