For the past few years I’ve used a Japanese Traveller’s Notebook as my daily diary. I liked it, and it was a useful tool while I tried to figure out what I really wanted and needed, but this year I ended up with a Hobonichi Techo — the smaller of the Japanese Hobonichi datebooks.
A representative page, with privacy redactions.
I love this thing! It’s exactly the right size for everything I want to record. It’s made of special, super-thin, super-strong paper (and costs like it!), so it’s light and durable. And I can write in it with my tiny fountain pen!
