In offering this little book to that public for which it is intended—a public made up of young men from fifteen to twenty years of age—the author fears that he may seem presumptuous. He intends to accentuate what most of them already know, not to teach them any new thing. And if he appear to touch too much upon the trifles of life, it is because experience shows that it is the small things of our daily intercourse with our fellow-beings which make the difference between success and failure. He gratefully acknowledges his obligation to the Reverend editor of the Ave Maria for permission to use in the last part of this volume several of the “Chats with Good Listeners.”
