It only takes a little bit of energy once a day (or per week if you haven't realized yet how eventful your life actually is). The highest energy first day making it is a fun date with your spouse, or parent child time if you are separated.

@parent don't get too worried about not writing in it religiously and having a schedule. That removes all the joy about doing it in the first place.

For example our 2026 notebook has only one page filled in yet where I wrote a recipe for a chocolate cake I made on the fly and was worried I'd forget the measurements.

There are some days when I am bored and I pick it up and backfill it as well.
