thesis statements

I would like to write my literary analysis paper on David Sedaris's "Me Talk Pretty One Day". I will analyze the idea of old age in the story and the idea of trying to have a fulfilling life. My thesis statement is proving itself difficult to write though. This is what I came up with.

In "Me Talk Pretty One Day" David Sedaris suggests how the fulfillment of life drives a person to do more to feel that accomplishment.
