I've looked at them a few times over the years but never bought one. They are pretty expensive - I guess from import duties etc. from Japan - and, you know, it's just a notebook. However, I saw that the 2H 2022 ones were up for pre-order at a local online store and so I went for it. Being half the year means that it was maybe half the price.
I could do all this with a blank notebook, and one at the fraction of the price. However, I quite like being told what to do. Like the defaults in software, good ones are well thought out and you’d be wise to at least try it that way.
My half year doesn’t start until 1st July, so I’m only partially using it right now. I’ll see how I get one once the month rolls around. I think it could be just what I’m looking for, or it could be that I’m romanticising a heap of paper.
