What I urge is that you so learn to control the machinery as to live with 'day-tight compartments' as the most certain way to ensure safety on the voyage. Touch a button and hear, at every level of your life, the iron doors shutting out the dead yesterdays and the unborn to-morrows.
What doth care about future events bring thee, save sorrow upon sorrow? Sufficient for the day is the evil thereof. It is vain and useless to be disturbed or lifted up about future things which perhaps will never come.
Money is human happiness in the abstract; he, then, who is no longer capable of enjoying human happiness in the concrete devotes himself utterly to money.
