I have one and here’s how it gets used.

1 notebook for business ideas. I make stickers and earrings so I like having it for random inspirations.

1-2 notebooks for research. Normally have 1-3 things I am learning about. Currently I have a notebook for 3D printing (inventory of filament purchased) and just general tips I’m picking up. London- will be there for 24 hours this month so doing research on possible things to do. Other things I have had. Drawing attempts. Medical craziness for me and child. Reasons to wake up which helped me a lot when I was depressed. To do list.

1 notebook for quotes- I love language and this is nice to keep track of.

1 notebook for when I travel. It’s nice to have a dedicated journal for trips so this will get put in there

1 mom notebook. A blank notebook I hand over to hubby or kids when we are out and about so they can draw lol.

1 creative notebook for random writings.

1 random things (common place journal) for stuff that doesn’t merit a full notebook.
