Which way is up?

My success ratio of using square Post- it notes is about 90%. Nine times out of ten, I get it right. One time out of ten, I get it wrong. How do I mess up using Post it notes? I forget to check which side the glue is on. No, I don’t stick my pen in the sticky, failure of an adhesive. I hold the block of notes at 90, 180 or 270 degrees in the wrong angle as I start writing.

The obvious solution is to be more mindful when writing notes. The less obvious solution is for 3M to start selling square Post-it notes with glue in all four corners.
