English essay thesis problem! plz help?

Question

my thesis is:
The universal theme or lesson of "A Good Man Is Hard To Find" by Flannery O'Connor is that all people should not judge themselves by what is on the outside but rather should look at what is on the inside because their appearance and inner self are not always same.

this is my thesis right now but I don't like the part saying "because their appearance and inner self are not always same."

any suggestions?

Additional Details

I know my thesis is long but this is how my teacher wanted so I can't change how it is set up.

Answer 2

Sounds a little long. How about, As we have learned from Flannery O'Connor, all people should not judge themselves on appearance, but what is on the inside. Short and sweet, expand on that idea through out the essay.
