The above quotation epitomizes the cure for neurasthenia, for as Huxley
said:

"Our life, fortune, and happiness depend on our knowing something of
the rules of a game far more complicated than chess, which has been
played since Creation; every man, woman and child of us being one of
the players in a game of our own. The board is the world, the pieces
the phenomena of the universe, while the rules of the game are the laws
of nature. Though our opponent is hidden, we know his play is fair,
just and patient, but we also know to our sorrow that he never
overlooks a mistake or makes the slightest allowance for ignorance. To
the man who plays well, the highest stakes are paid with that
overflowing generosity with which the strong show their delight in
strength. The one who plays badly is checkmated; without haste, but
without remorse. Ignorance is visited as sharply a as wilful
disobedience; incapacity meets with the same punishment as crime."

In many cases some real trouble is the best medicine for a neurasthenic,
for though disaster may crush him, it is more likely to act as a spur, by
diverting his thoughts from his woes, and making him fight instead of fret.

Since such blessings in disguise cannot be booked to order, first see a
doctor. Though little be physically wrong, the sense of comfort and relief
from fear, which a clear idea of what _is_ wrong brings, goes a long way
towards cure by giving the patient hope and confidence.

Having seen the doctor, assist him by carrying out the following advice as
