Artists: drawing portraits has really helped you see that everyone has their own type of beauty, amirite?

Good god, yes.
I remember I used to draw the same faces. Perfectly perfect faces. My art teacher, realizing my lack of creativity, then gave me two pictures of two different models to draw from, and just from that I learned there's more to faces.
Then she introduced me to Mucha. Good god, all the different facial types. So averagely beautiful.

For me, it was the most amazing discovery I ever made in art.
