Man falls from the pursuit of the ideal of plan living and high thinking the moment he wants to multiply his daily wants. Man's happiness really lies in contentment.
This is the true joy of life-the being used for a purpose recognized by yourself as a mighty one, the being thoroughly worn out before you are thrown to the scrap-heap; the being a force of nature instead of a feverish, selfish clod of ailments and grievances.
If happiness always depends on something expected in the future, we are chasing a will-o'-the-wisp that ever eludes our grasp, until the future, and ourselves, vanish into the abyss of death.
Life at its noblest leaves mere happiness far behind; and indeed cannot endure it. Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.
It is the activity of the intellect that constitutes complete human happiness - provided it be granted a complete span of life, for nothing that belongs to happiness can be incomplete.
