Readers may be divided into four classes:
1.) Sponges, who absorb all that they read and return it in
nearly the same state, only a little dirtied.
2.) Sand-glasses, who retain nothing and are content to get
through a book for the sake of getting through the time.
3.) Strain-bags, who retain merely the dregs of what they read.
*************4.) Mogul diamonds, equally rare and valuable, who profit by
what they read, and enable others to profit by it also.
~ Samuel Taylor Coleridge ~
But to be frank, and give it thee again.
And yet I wish but for the thing I have:
My bounty is as boundless as the sea,
My love as deep; the more I give to thee,
The more I have, for both are infinite. Juliet ( Shakespeare )
