Thanks for all your helpful hints again, Nola. I always print out anything I am working on after the initial check on the computer. I see things much better on hard copy. I go and sit in a comfy chair to check the hard copy - this actually helps for me!
Thanks Jeanette. That's a good point about reading where you're comfortable. I use a desk easel to prop up anything I'm proofreading so I don't get a sore neck. Anything to aid comfort can help with concentration. Thanks for sharing.
