So the conventional bullet journal wisdom is that if you keep everything in one journal you will always know where everything is, it integrates your life, etc. But recently I started an art notebook to keep track of ideas for paintings and it quite rapidly turned into a kind of bullet journal.
So my question is: do you use just one journal at a time, or do you have several on the go at once?
What do you put in a different journal? And what do you like about your approach?
