Well first of all there are a few safety precautions I would have to write down.

• The notebook can never be taken from me.
• I will always know where the notebook is.
• No one but me can use the notebook.
• The notebook is indestructible.
• The notebook will never run out of pages to write on.
• I will always be able to summon a pen to write in the notebook with.
• I can never be harmed or restrained against my will by anything or anybody.

Then the real fun could begin.
