The secret of health for both mind and body
is not to mourn for the past,
not to worry about the future,
nor to anticipate troubles,
but to live in the present
moment wisely and earnestly.
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.
