After just a few days I've found myself not being able to figure out at a glance what's next and having to go back and forth the notes. That even if I've spent the time to inter-link things. But at this point I should also mention that in my role (product manager) I have quite a few projects on my plate at all time and a month long list of things is usually in the high tens/hundred items (and doesn't include meetings).
I was really attracted by the BulletJournal system as it felt in a way similar to what I've been using, but with a nicer/cleaner visual representation. Basically I have my long list of things in a tool. Every Monday I spend a bit of time extracting what's the focus for the week into a separate file. In this file I also log daily activity. At the end of the week there's a short review and then I'm archiving the week.
