I use obsidian for journaling and doing actual work. 10/10, I don't need anything else there, markdown is a breeze. I couple that with Google Calendar as a sort of "digital agenda", in the sense that I take notes right in there, next to events and etc (no "keep" nor any other app). It's horribly cumbersome (for it's not what it's made for), yet 110% effective at making sure I don't forget anything, both because everything is in just one same place, and because I can move important notes forward so that they appear right in my face at the right time (be it when I start working, or when I estimate I will arrive home, etc). Plus that same ordering capability (in a same day and along days) serves as a sort of kanban, to classify and establish priorities of the notes, right in the same place I organize the tasks they relate to (if even, sometimes it's just the notes). It makes it impossible to miss anything, and that lightness and peace of mind greatly offsets the cumbersomeness.
