That fact will be emphasized again and again in this book. I stress it here in tribute to the source of my prudence. Safety first has been my guiding star. A Scotch mother is the greatest asset a boy can have who desires a career in advertising. Then economy and caution are instinctive with him. They are fundamwtals. Success, save by accident, is impossible without them. But the lack of these qualities may be partially corrected by studious cultivation. Most business wrecks which I have encountered are due to over-reaching. TO reckless speculation on a hidden chance. To that haste which laughs at conservatism. To racing ahead on unblazed trails, in fear that some rival may go farther or get higher.
