six o'clock
I hear a good deal about men who wo n't take vacations , and who kill themselves by overwork , but it 's usually worry or whiskey . It 's not what a man does during working-hours , but after them , that breaks down his health . A fellow and his business should be bosom friends in the office and sworn enemies out of it . A clear mind is one that is swept clean of business at six o'clock every night and is n't opened up for it again until after the shutters are taken down next morning . Some fellows leave the office at night and start out to whoop it up with the boys , and some go home to sit up with their troubles -- they 're both in bad company . They 're the men who are always needing vacations , and never getting any good out of them . What every man does need once a year is a change of work -- that is , if he has been curved up over a desk for fifty weeks and subsisting on birds and burgundy , he ought to take to fishing for a living and try bacon and eggs , with a little spring water , for dinner .
