The four types of readers: (According to Samuel Taylor Coleridge)

One possible source

Readers maybe divided into four classes:

1. Sponges, who absorb all they read, and return it nearly in the same state, only a little dried.
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 diamond, equally rare and valuable, who profit by what they read, and enable others to profit by it also.

The original text might be found on Google books: Digital Scrapbook by Austin Kleon

The other source

“There are four kinds of readers. The first is like the hourglass; and their reading being as the sand, it runs in and runs out, and leaves not a vestige behind. A second is like the sponge, which imbibes everything, and returns it in nearly the same state, only a little dirtier. A third is like a jelly bag, allowing all that is pure to pass away, and retaining only the refuse and dregs. And the fourth is like the slaves in the diamond mines of Golconda, who, casting aside all that is worthless, retain only pure gems.”  Taylor Coleridge > Quotes > Quotable Quote

He also said the same thing here.

The similar ideas are articulated by Bill Gates.
