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.
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.
