Wattles (1860-1911) was the author of, among other things,

every business transaction.
Guard you speech. Never speak of yourself, your affairs, or
of anything else in a discouraged or discouraging way. Never

failure as a possibility. Never speak of the times as being
hard, or of business conditions as being doubtful. Times may
be hard and business doubtful for those who are on the
competitive plane, but they can never be so for you; you can
create what you want, and you are above fear. When others
are having hard times and poor business, you will find your
