Whenever I am a little low, I go to one place for sure- it is the library in my home. The books that I have bought or got as gifts are just like friends to me.
So it is our duty to keep the bookcases that hold such a wealth of information free from dust. Regular dusting of these bookshelves and all other furniture in general really acts as a therapy as you end up getting a sparkling clean home in minutes. The layer of dust gathered on your shelves will surely create a bad impression. Your home needs care too!
