Successful men, in all callings, never stop acquiring specialized knowledge related to their major purpose, business, or profession. Those who are not successful usually make the mistake of believing that the knowledge acquiring period ends when one finishes school. The truth is that schooling does but little more than to put one in the way of learning how to acquire practical knowledge. Experience has proven that the best-educated people are often those who are known as “self-made,” or self-educated. It takes more than a college degree to make one a person of education. The person who stops studying merely because he has finished school is forever hopelessly doomed to mediocrity, no matter what may be his calling. The way of success is the way of continuous pursuit of knowledge.
