A stoicly mindful productivity system

The ornate, time consuming and questionably useful "spreads" that are, unfortunately, the most common introduction to "bullet journaling" obscure a thoughtfully designed framework, the aim of which seems to be helping people understand themselves better.
This book does a much better job of laying out the foundations and showing how to adapt the system to your own needs. Behind it all is a fusion of stoic philosophy, mindfulness and pop psychology, delivered in a fairly restrained fashion. While the book is clearly trying to sell you on the merits of the system, it sticks to testimonials and personal anecdotes rather than evangelical lectures.
I think I'd have liked a bit more insight into how he came to this formulation and the history of its development but there are some allusions sprinkled throughout.
Definitely worth a read if you find productivity systems like gtd or konmari interesting. Otherwise you probably already know if this is worth your time or not.
