what guiding principles of life did booker t washington develope in his stay at hamptom institute explain how they developed and why he offered them as advice for others

I'm not certain which section in the book you're working on, but while at Hampton, Booker learned certain things that he carried with him throughout his life. He learned that the happiest people are those who serve others, the value of reading the Bible, and the dignity to be found in labor. This information comes from Chapter Four. If this question pertained to a different chapter, please let me know.
