No greater mistake could be made than to curtail the hours of
sleep. Eight hours should be taken as a minimum, and any weak person
should take ten hours. More and better work can be done by a person who
takes fully eight hours' sleep than by one who tries to do with less.
Sometimes strong tea or coffee is taken to drive away sleep, and so the
nervous system is injured and sleep will not come when it is desired.
Tea or coffee should never be taken except very weak, and the person
who accustoms himself to this will very soon come greatly to prefer it.
