Have you ever felt desperate? Not desperate to find disposable diapers at midnight when you realized you just used the last one and your baby has diarrhea? And not desperate to find your car keys. I mean desperate to find a way for your hero to escape the wooden box sinking in the middle of the ocean desperate.
As your character sinks to the bottom of the ocean, and as the air supply at the top of the wooden box gets smaller you grab your head in your hands and pace the floor frantic to save your hero’s life before his air supply runs out.
You try jumping jacks to stimulate oxygen to your brain. You do a google search for ideas to break writer’s block and then do you everything they suggest.
