So what do you find useful when writing with pencil and paper?

I need a pencil and a hard surface to write. This is usually the clipboard. I can also use a hardcover notebook. I would love to have a hardcover so I can move the pages, delete and scan, etc., but so far I have only found soft plastic or soft cardboard. A kneeling desk can also be very useful.

 

I rarely use any services, but it seems to me that it's time to try. These are mainly wikipedia or educational forums. If I need to test some writing theory, I buy essays online. These are my decisions.
