“Touch a button and hear, at every level of your life, the iron doors shutting out the Past the dead yesterdays. Touch another and shut off, with a metal curtain, the Future the unborn tomorrows. Then you are safe, safe for today! Shut off the past! Let the dead past bury its dead. Shut out the yesterdays which have lighted fools the way to dusty death. The load of tomorrow, added to that of yesterday, carried today, makes the strongest falter. Shut off the future as tightly as the past. The future is today. There is no tomorrow. The day of man's salvation is now. Waste of energy, mental distress, nervous worries dog the steps of a man who is anxious about the future. Shut close, then the great fore and aft bulkheads, and prepare to cultivate the habit of life of 'day-tight compartments.”
