that you worry about these
things to which I have referred, that you yield your thoughts to them,
and, in your worry, give undue contemplation to them, induces the
conditions you wish to avoid or avert. Hence, if you wish your child
to be well and strong, brave and courageous, it is the height of
cruelty for you to worry over his health, his play, or his exercise.
Better by far leave him alone than bring upon him the evils you dread.
Who has not observed, again and again, the evil that has come from
worrying mothers who were constantly cautioning or forbidding their
children to do that which every natural and normal child longs to
do? Quit your worrying. Leave your child alone. Better by far let
him break a rib, or bruise his nose, than all the time to live in the
bondage of your fears.

Elsewhere I have referred to the fact that we often bring upon our
loved ones the perils we fear. There is a close connection between
our mental states and the objects with which we are surrounded.
Or, mayhap, it would be more correct to say that it is our mental
condition that shapes the actions of those around us in relation to
the things by which they are surrounded. Let me illustrate with an
incident which happened in my own observation. A small boy and girl
had a nervous, ever worrying mother. She was assured that her boy
was bound to come to physical ill, for he was so courageous, so
adventuresome, so daring. To her he was the duck instead of the
chicken she thought she was hatching out. One day he climbed to the
roof of the barn. His sister followed him. The two were slowly, and
in perfect security, "inching" along on the comb of the roof, when the
mother happened to catch sight of them. With a scream of half terror
and half anger, she shouted to them to come down _at once!_ Up to
that moment, I had watched both children with comfort, pleasure, and
assurance of their perfect safety. Their manifest delight in their
elevated position, the pride of the girl in her pet brother's courage,
and his scarcely concealed surprise and pleasure that she should dare
to follow him, were interesting in the extreme. But the moment that
foolish mother's scream rent the air, everything changed instanter.
Both children became nervous, the boy started down the roof, where he
could drop upon a lower roof to safety. His little sister, however,
started down too soon. Her mother's fears unnerved her and she slid,
and falling some twenty-five feet or so
