“What I urge is that you learn to master you life by living each day in a day-tight compartment and this will certainly ensure your safety throughout your entire journey of life. 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.
Think not of the amount to be accomplished, the difficulties to be overcome, but set earnestly at the little task near your elbow, letting that be sufficient for the day; for surely our plain duty is not to see what lies dimly at a distance but to do what lies clearly at hand.” Spoken by Sir William Osler to the students of Yale University
