I have tried a *lot* of journal modalities over the years. It took a while to find what I liked best! you should definitely explore lots of options. The thing for me turned out to be a bunch of different md files for different "subjects"; if a consistent theme starts to show up in my work journal or my personal journal (the two main ones), I'll "bud off" another journal just for that. For instance, I did that for voice training and for writing my dissertation. Also, I have a fairly elaborate way of processing my to-do list from one day to the next: I described it to a labmate of mine the other day and apparently I independently invented bullet journaling??
