Chap. 4-5 His writing

Why does Wright feel gratified after sharing his writing?

I believe that he feels gratified because he feels that he has accomplished something in his life. He had alot of troubles with his family and now he feels good about something. He also finally feels good with his self instead of being hastled and judged by his grandma. Wright feels since he shared his writing he now has confidence and is a good writer. In the book this scene shows that Wright is growing older and more mature.
