Value of "wasted time" to spark creativity

Mechanical beast put out to pasture

I enjoyed listing to author, Jonah Lehrer, on Minnesota Public Radio yesterday speaking about creativity.  Among other things he noted that Albert Einstein once observed that creativity is the residual of wasted time.

One of the under discussed keys to creativity is a feeling of frustration with an inability to find an answer to a problem.  Then with time, often when we are relaxed, an elegant solution arrives at a time least expected.

Mr. Lehrer has written a book "Imagine: How Creativity Works."

A high school classmate observed between his studies... "Time you enjoy wasting is not wasted time."
