The injurious effect upon the nervous system of these faulty mental states
has been emphasized, together with their influence as potent underlying
causes of so-called nervous prostration, preparing the worrier for
breakdown from an amount of work which, if undertaken with tranquil mind,
could have been accomplished with comparative ease.

The question is, will the possessor of these faulty mental tendencies grasp
the importance of giving thought to the training that shall free him
from the incubus? He certainly has the intelligence, for it is among the
intelligent that these states are mostly found; he certainly has the
will-power, for lack of will-power is not a failing of the obsessed. The
question is, can he bring himself to make, at the suggestion of another,
a fundamental change of attitude, and will he take these suggestions on
faith, though many seem trivial, others, perhaps, unreasonable, and will he
at least give them a trial? I hope so.

In the next sections will be summed up such commonplace and simple
suggestions as may aid emergence from the maze of worry. Many of the
suggestions have been scattered through preceding sections. The worrier and
folly-doubter is more likely to be benefited by trying them than by arguing
about them, and it is within the realms of possibility that some may come
to realize the truth of the paradox that he who loses himself shall find
himself.
