Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.
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.
