OK, we'll start with a stop. Stop reading and look around your space. Then come back.
(La-de-dah-de-dah-de-doo .... Oh! You're back. Good.)
Now, tell me, how long has it been since you rearranged things? Put up a new photo? Pinned a new note to the bulletin board? If it's been a month or more, take a minute and make a change.
I just found my lost Groucho glasses. Instead of putting them away with my other creativity props, I put them on display in my bookcase. Every time I walk into the office, the glasses make me laugh. In another week or two, I won't notice them ... but right now, they're new. And new sparks brain cells. And brain cells spark creativity. See where I'm going? Oh, you are good.
Change your space.
