You know when you’re studying, or reading, or doing a puzzle, and your brain kind of stops working? It’s time to change your field of vision.

If you can, stand up and go outside and look as far away as you can. If you can’t do that, look out a window. Find somewhere to focus your view that’s far away for 30 seconds or a minute.

When you look back at your work, I bet you’ll find your brain is working again. Do this whenever you find your thoughts slowing down.
