ELI5: Why is it when a person forces and mentally prepares him/herself to write something creative the mind is usually blank where as when he/she isnt actually thinking about it the mind is full of creativity?

When you're focusing, you're engaging the parts of your brain that handle step-by-step tasks like math. Creative efforts take specific skills to do, like drawing is a fine motor skill, but to get the ideas for that creative effort you have to use the parts of your brain that handle things like daydreaming. The daydreamy parts of your brain basically turn off when you're focused on a step-by-step type of task (unless it's a very very boring task that you've done so much you could do it with your eyes closed, like putting boxes together or folding clothes).

Basically, your brain is kind of like a computer that can do your taxes and can play video games but it can't run the video games if the taxes program is already running.
