The art of living does not consist
in preserving and clinging
to a particular mood of happiness,
but in allowing happiness
to change its form without
being disappointed by the change;
for happiness, like a child,
must be allowed to grow up.
Try to be happy in this present moment, and put not off being so to a time to come,—as though that time should be of another make from this which has already come and is ours.
