“We have all met a class of men, very remarkable for their activity, and who yet make but little headway in life; men who, in their noisy and impulsive pursuit of knowledge, never get beyond the outer bark of an idea, from a lack of patience and perseverance to dig to the core; men who begin everything and complete nothing; who see, but do not perceive; who read, but forget what they read, and are as if they had not read; who travel but go nowhere in particular, and have nothing of value to impart when they return.”
