Im looking for songs that are about accepting yourself or having confidence?

Im not interested in older songs or songs that have anything to do with relationships (even if its being stronger after a relationships) some examples are; "superwoman" by alicia keys, "freckles" by Natasha Bedingfield,"video" , "I am not my hair" by India arie, and "finding my way back home" by Lee ann womack. They dont have to be by women, any genre and preferably upbeat. THANKS!! any help would be GREATLY appreciated!
