Here is a little note from grammarly.com. There is nothing special in these tips, of course, but still- it drives my attention to my little faithful soldiers – commas, full stops. semicolons, articles. I look down at them like a general looks at his army from the top of a hill. I talk to my “soldiers” while I work, I give them orders: “Stay here!” or “What are you doing here? Move to the end of the sentence!” This is my way of surviving through the boredom of proofreading. What is yours?
