be  grateful    music   to  our ears    when    we  are in  one mood,   and excruciatingly
discordant  noise   when    we  are in  another.    What    appeals to  us  as  a   good    practical
joke    one day,    may seem    a   piece   of  unwarranted impertinence    on  another.    A
proposition which   looks   entirely    plausible   under   the sanguine    mood    induced by
a   persuasive  orator, may appear  wholly  untenable   a   few hours   later.  Decisions
which   seemed  warranted   when    we  were    in  an  angry   mood,   often   appear  unwise
or  unjust  when    we  have    become  more    calm.   Motives which   easily  impel   us  to
action  when    the world   looks   bright, fail    to  move    us  when    the mood    is  somber.
The  feelings    of  impending   peril   and     calamity    which   are     an  inevitable
accompaniment    of  the     "blues,"    are     speedily    dissipated  when    the     sun     breaks
through the clouds  and we  are ourselves   again.
Mood    Influences  Effort.—A   bright  and hopeful mood    quickens    every   power
and enhances    every   effort, while   a   hopeless    mood    limits  power   and cripples
effort. The football    team    which   goes    into    the game    discouraged never   plays   to
the limit.  The student who attacks his lesson  under   the conviction  of  defeat  can
hardly  hope    to  succeed,    while   the one who enters  upon    his work    confident   of  his
power   to  master  it  has the battle  already half    won.    The world's best    work    is  done
not by  those   who live    in  the shadow  of  discouragement  and doubt,  but by  those
in  whose   breast  hope    springs eternal.    The optimist    is  a   benefactor  of  the race    if
for no  other   reason  than    the sheer   contagion   of  his hopeful spirit; the pessimist
contributes neither to  the world's welfare nor its happiness.  Youth's proverbial
enthusiasm   and     dauntless   energy  rest    upon    the     supreme     hopefulness     which
characterizes   the mood    of  the young.  For these   reasons,    if  for no  other,  the mood
of  the schoolroom  should  be  one of  happiness   and good    cheer.
Disposition a   Resultant   of  Moods.—The  sum total   of  our moods   gives   us  our
disposition.    Whether these   are pleasant    or  unpleasant, cheerful    or  gloomy, will
depend  on  the predominating   character   of  the moods   which   enter   into    them.   As
well    expect  to  gather  grapes  of  thorns  or  figs    of  thistles,   as  to  secure  a   desirable
disposition out of  undesirable moods.  A   sunny   disposition never   comes   from
gloomy  moods,  nor a   hopeful one out of  the "blues."    And it  is  our disposition,
more    than    the power   of  our reason, which,  after   all,    determines  our desirability
as  friends and companions.
The  person  of  surly   disposition     can     hardly  make    a   desirable   companion,  no
matter  what    his intellectual    qualities   may be. We  may live    very    happily with    one
who cannot  follow  the reasoning   of  a   Newton, but it  is  hard    to  live    with    a   person
chronically subject to  "black  moods." Nor can we  put the responsibility  for our
disposition off on  our ancestors.  It  is  not an  inheritance,    but a   growth. Slowly,
