Explanation:
In "A Cub Pilot", Mark Twain narrates the true experiences he had piloting on the Mississippi River as a young boy. On of the most important lessons his boss, Mr. Bixby, taught him was to never doubt himself. Instead, Twain learned to trust his skills, to have confidence in his capabilities.
