I prefer to minimize the waste I generate with my daily activities. A reusable notebook sounds ideal for me. I don't use paper for this very reason.

Some reasons off the top of my head:

* I can scribble group meeting notes and share them in Slack by just scanning from my phone and they come out great—including drawings

* I can scan my notes quickly as PDFs and keep them for years to come

* Some classes allow me to upload and refer to my notes during exams

* I don't waste any paper

Points 1,2,3 apply to paper notebooks, too.

As for wasting paper, even in my furious note taking days in college, it didn't amount to that much paper. I don't think the stack after graduating reached a foot high. You'll waste orders of magnitude more paper throwing away junk mail, food packages, etc. Besides, paper recycles easily. Plastic rocketbook pages, nope.

They do, but the accompanying app with RocketBook makes it easier. Each page has customizable bubbles which I can tick off to send the notes to the right destination. It just works which is unusual with most technology.

Additionally, when I was in my undergrad I still went through a lot of paper. I have bad habits when I scribble notes or solve math problems. But with this, it's the only notebook I carry.

I don't have separate notebooks for work, subjects, home, etc.
