I had been keeping myself productive both at work and home. with the Bullet Journal method for about six months before my husband died. Looking at it, it's like a textbook example of a disorganizing brain event.
Before: tidy lists and columns, checkmarks, thorough notes, organized progress. After: scrawls all over the page, no dates, forget the bullets, no checkmarks, days at a time skipped. I can't even remember where my bullet journal notebook is half the time.
