A perfectly healthy body will shed germs of disease without ever
feeling their presence. So a perfectly healthy mind will shed the
germs of sentimentality. Few of us are so healthy in mind but that
we have to recognize a germ or two and apply a disinfectant before
we can reach the freedom that will enable us to shed the germs
unconsciously. A good disinfectant is, to refuse to talk of our own
feelings or desires or affections, unless for some end which we know
may help us to more light and better strength. Talking, however, is
mild in its weakening effect compared with thinking. It is better to
dribble sham sentiment in words over and over than to think it, and
repress the desire to talk. The only clear way is to drop it from
our minds the moment it appears; to let go of it as we would loosen
our fingers and drop something disagreeable from our hands.

A good amount of exercise and fresh air helps one out of
sentimentalizing. This morbid mental habit is often the result of a
body ill in some way or another. Frequently it is simply the effect
of tired nerves. We help others and ourselves out of it more rapidly
by not mentioning the sentimentalizing habit, but by taking some
immediate means towards rest, fresh air, vigorous exercise, and
better nourishment.

Mistakes are often made and ourselves or others kept an unnecessary
length of time in mental suffering because we fail to attribute a
morbid mental state to its physical cause. We blame ourselves or
others for behavior that we call wicked or silly, and increase the
suffering, when all that is required is a little thoughtful care of
the body to cause the silly wickedness to disappear entirely.
