I have incidentally mentioned the vast expanse of forty-four hours between leaving business at 2 p.m. on Saturday and returning to business at 10 a.m. on Monday. And here I must touch on the point whether the week should consist of six days or of seven. For many years--in fact, until I was approaching forty--my own week consisted of seven days. I was constantly being informed by older and wiser people that more work, more genuine living, could be got out of six days than out of seven. And it is certainly true that now, with one day in seven in which I follow no programme and make no effort save what the caprice of the moment dictates, I appreciate intensely the moral value of a weekly rest. Nevertheless, had I my life to arrange over again, I would do again as I have done. Only those who have lived at the full stretch seven days a week for a long time can appreciate the full beauty of a regular recurring idleness. Moreover, I am ageing. And it is a question of age. In cases of abounding youth and exceptional energy and desire for effort I should say unhesitatingly: Keep going, day in, day out. But in the average case I should say: Confine your formal programme (super-programme, I mean) to six days a week. If you find yourself wishing to extend it, extend it, but only in proportion to your wish; and count the time extra as a windfall, not as regular income, so that you can return to a six-day programme without the sensation of being poorer, of being a backslider. Let us now see where we stand. So far we have marked for saving out of the waste of days, half an hour at least on six mornings a week, and one hour and a half on three evenings a week. Total, seven hours and a half a week. I propose to be content with that seven hours and a half for the present. "What?" you cry. "You pretend to show us how to live, and you only deal with seven hours and a half out of a hundred and sixty-eight! Are you going to perform a miracle with your seven hours and a half?" Well, not to mince the matter, I am--if you will kindly let me! That is to say, I am going to ask you to attempt an experience which, while perfectly natural and explicable, has all the air of a miracle. My contention is that the full use of those seven-and-a-half hours will quicken the whole life of the week, add zest to it, and increase the interest which you feel in even the most banal occupations. You practise physical exercises for a mere ten minutes morning and evening, and yet you are not astonished when your physical health and strength are beneficially affected every hour of the day, and your whole physical outlook changed. Why should you be astonished that an average of over an hour a day given to the mind should permanently and completely enliven the whole activity of the mind?
