What is the author's style in Education of a Wandering Man by Louis L'Amour?

Although L'Amour's lack of bitterness over having missed out on a formal education is obvious, one cannot help but think that his demeanor was perhaps not as happy-go-lucky as it was portrayed in his memoir. At sixteen as he is pretending to be a twenty-two year-old, he is hanging out in a British pub with a crew of seasoned seamen and ruffians while he thinks of his high school classmates readying themselves for graduation. At such a tender age, there had to be a tinge of regret that he wasn't with his friends. He had to feel lonely and somewhat abandoned.
