Know them, understand them, then defy them to destroy your happiness.

If you can't dust your house daily, dust it thrice a week, or twice, or once, and determine that you will be happy in spite of the dust.

The real comfort of the house need not thereby be impaired, as there is a vast difference between your scrupulous cleanliness and careless untidiness.

Things may be in order even though the floor has a little extra dust on, or the furniture has not been dusted for four days.
"But," you say, "I am far less disturbed by the over work than I am by the discomfort that comes from the dust." Then all I can say is that you are wrongly balanced, according to my notion of things.

Your health should be of far more value to you than your ideas of house tidiness, but you have reversed the importance of the two.
