1913. This little book is not written so much for geniuses, or those who have had exceptional opportunities in life, as for persons of ordinary ability who have had only everyday opportunities. The men who have left their mark on the world seized common occasions and made them great. There have been but few great geniuses. It has never been men of ordinary ability and common virtues, with uncommon application, with supreme determination and persistence, who have won the great prizes of life.
