When you look at everything rightside up, all the time, you see pretty much the same thing, all the time. Which is why I will at times write in my journal in a wide circle, or spiral, or wavy line, or upside down. Yes, one needs unlined pages for this. And there is risk. One might write crookedly! Gasp!
But the upside down thing shakes off your critical mindset, and opens you to new ideas. Which is why Betty Edwards recommends drawing upside down, in Drawing on the Right Side of the Brain, which has wonderful parallels for writing or any other creative endeavor.
Put your words down in different visual format than you're used to. Write sideways. Type upside down.
