Sometimes, inspiration strikes when we're doing the menial tasks around the house.
Doing the dishes, doing the laundry, mowing the grass, feeding the dog, picking up groceries, and so on.
They're not the most fun activities. But they're also opportunities to distract ourselves so new ideas can come to mind.
They can become a creative meditation of sorts.
So when you're stuck looking for ideas, take a break. Do the dishes.
See what you come back with.
