I have had many of these same experiences. I have learned to use the experience to learn or develop work-arounds. First, I know I need to slow down.I also set up my tasks in a very visual format. If I need to work with multiple papers, I need to 3 hole punch them and put them in binders. I put a index in the front of the binder.

I know I can not rely on my memory. When I was trying to put together a Work Comp claim, I printed many pages too many times. By the time I was done, I had a binder full of the extra pages. This task is what taught me to establish work-around systems.

In time, you will slowly learn how to prevent most of these "brain farts."

Then, when they do happen, you can just have to laugh.

I agree about putting them away for next year. That way you will find them the week after you printed out another set. LOL

Hang in there. You will continue to learn new skills and things will get better.

My best to you.
