Those who face that which is actually before them, unburdened by the past, undistracted by the future, these are they who live, who make the best use of their lives; these are those who have found the secret of contentment.
The failure of the mind in old age is often less the results of natural decay, than of disuse. Ambition has ceased to operate; contentment bring indolence, and indolence decay of mental power, ennui, and sometimes death. Men have been known to die, literally speaking, of disease induced by intellectual vacancy.
