How do you use your notebooks?

Until a few days ago, I’d never really thought about this before, but I noticed I have a very definite way in which I use notebooks. I’m going to name it the Mullet technique, i.e. business in the front, party in the back. When I say party though, I kind of just mean messy…

I have 2 main notebooks on the go at the moment and it’s exactly the same for both.

My Moleskine, which I keep at home

Front (neat):

Back (messy):

And my Field Notes, which I carry in my bag

Front (neat):

Back (messy):

I clearly make a subconscious decision as to whether what I’m writing is deemed “important” or not, before starting the front or back… Although looking through them, some of my decisions seem quite random!

I’m curious – does anyone else do this? Do you set yourself weird criteria? Or do you have different notebooks for different things; to do lists, messy work etc. Let me know!
