As for goals, Olive's goal was to go to the Little Miss Sunshine pageant and compete, and that was her main focus the whole time. With Richard, his main focus seemed to change. At first he was all in for taking Olive (and the rest of the family) to the pageant, then he was focused on getting his business deal, then he was focused on stealing grandpa's body, then he was back to getting Olive to the pageant and having her compete, and finally, he wanted Olive and the rest of his family to be happy and be who they want to be.
Both of them are so different at the beginning and seem to have completely different mid sets, but what I loved, was at the end of the movie, everyone came together and they seemed to all be on the same page. Everyone seemed happy and at peace, and I really enjoyed that.
