What does Zora Neale Hurston’s last line mean?

The quote to the left is from Zora Neale Hurston’s essay entitled “How It Feels to Be Colored Me”.
She begins by stating: I am colored but I offer nothing in the way of extenuating circumstances except the fact that I am the only Negro in the United States whose grandfather on the mother’s side was not an Indian chief.
I think the piece really embodies my take on the idea we can only be who we think we are. But I wonder what it means to you?
Let me know what you think of any part of Ms. Hurston’s essay?
