Kenny Rogers would say, "You've got to know when to hold 'em, know when to fold 'em."
Buddha might say, "Inaction is the most important part of action."
And about 14 years ago while working as a writer for the New England Aquarium, I wrote a piece for Boston museum PR writers. On writer's block, I wrote, "When in doubt, go to the restroom." Truth: I've found some of my best writing solutions halfway between my desk and the office toilet.
There's nothing better than a well-timed break. Knowing when to take it is key.
Just remember to keep your eyes open on the way to the potty.
