Rather than going off topic I find a quick break into inspiring art, poetry or music to be a stimulation, a sorbet to clear the pallet.

Archimedes made his greatest discovery while relaxing in the bath.
When did your greatest marketing revelation occur to you?
While you where struggling at your keyboard?
Or while you were relaxing?
