Thanks for the echo, Kurt. Your description is exactly correct.
It is laughable to think about the consequences of this work habit: "I tend to leave documents that I have duplicated open for a while in case I need to refer to them later. Only when I'm fairly sure I am OK with not having to go back do I close them off."
As someone who works with dozens, maybe hundreds of documents daily, it is awe-inspiring to imagine what it would be like to look over his shoulder and watch him do his work. What is "a while" ... a few minutes? A week?
If I am ever fairly sure I am OK with never having to go back to something, then I don't even consider saving it, I throw it in the trash! Why save any documents at all? Why not just leave them all open and unsaved, scattered all over your computer screen?
OMG. Woody Allen had a way to describe that mentality but I won't repeat it here.
