My technological breakthrough

I discovered an exciting new tool that I'm evaluating, both at work and at home, that I wanted to tell you about: a blank sheet of paper and a pen.

Why not a pencil? When I use a pencil, I spend time correcting my mistakes, and mental energy deciding whether I should correct my mistakes. If I start making too many mistakes with a pen, it alerts me that I need to slow down.

This tool very inexpensive. You don't have to buy expensive fountain pens, fancy inks, and European paper to do this. (But I did, of course. If your curious about what I found out while doing this, please ask questions in the comments.)
