I've always been interested in self-knowledge and I'm seriously considering giving this a try after listening to Peterson's intro video. I've found my own attempts at journaling have come in fits and starts as I find the motivation to do so, which is rare these days. Other than the initial outpouring of insight when I first started doing it, I haven't found much benefit as time went on. I'll have to seriously consider giving this a go. My only apprehension is with the time commitment. Maybe I'll have to make some. Seems pretty important.
