The glut of information means that we need to review things more than ever.
And one of the most useful tools I've come across is Readwise.
Each day or weekly (up to you), it emails you a dose of your Kindle and Instapaper highlights.
Rereading through them not only reminds you of the interesting passages you once discovered, but also how that “old” information connects to your existing thinking.
According to professor Kenneth Goldsmith at the University of Pennsylvania, “an educated person in the future will be a curious person who collects better artifacts. The ability to call up and use facts is the new education. How to tap them, how to use them.”
The pennies of Instapaper or Pocket articles you collect add up over time but their meaning is in their extraction. The simple act of reviewing allows one to remix and convert previously found artifacts into forward-thinking idea-generating value.
