Success Happy

What are some songs that have numerous lyrics about being intelligent and happy with who you are?

I need this for a English project about me, please give a song that has stuff about a common man's life too if you can

1. Well, it's about a common WOMAN, but the song No Regrets by Atmosphere is a good one.
2. Waltz (better than fine) - Fiona Apple http://www.youtube.com/watch?v=K101lypWO0U
