Perhaps the most important factor in a successful vocabulary-building program is motivation. It will be very difficult for you to study words month after month without a strong feeling that it is worth doing, that a larger vocabulary will help you in school and on the job, and that it can well lead to a more exciting and fulfilling life. We certainly feel that this is true, for nothing we measure at the Johnson O'Connor Research Foundation contributes more to success in life more than vocabulary. Your time could not be better spent.
