I don't believe in self-improvement, but there are always other people whose visioning suggests I'm improvable. These people give me books on organization, improving my temperament, taking charge of my inner Mars and Venus while moving cheese around effortlessly and thinking outside the box. I should write a book on how to live better by overcoming the addiction to self-improvement. It's still in the visioning stage. The self-help world suggests visioning through journaling.
Nobody keeps a journal anymore, they journal instead.
Oddly, I know few journalists who journal. I don't journal. Journaling is a visioning exercise. Columning, by contrast, is often a de-visioning exercise. A reaction to dumb visioning by others.
