"The most thunderous sound arises out of quietude." - Zhaungzi

"The monotony and solitude of a quiet life stimulates the creative mind." - Albert Einstein

"If you don't have time to read, you don't have the time (or the tools) to write. Simple as that." - Stephen King

In other words unplugging, making time to read books, and allowing yourself to be bored are all good ways to stimulate the creative mind.
