The Bullet Journal Method

The system is good, this book is okay.

Part I “The Preparation” is your standard throw-away lead-in stuff about why anyone should track/journal and Ryder's origin story.

Part II “The System” is where all the good stuff is, about how to actually bullet journal.

Part III “The Practice” gets pretty life-coachy about goal setting, stoicism, wabi sabi, finding meaning, acknowledging mortality, etc.

Part IV “The Art” offers some tips to non-beginners about how to optimize things.

Overall I'd say if you just want to get a solid grasp on HOW to bullet journal, you don't need this book. Just read a blog post on how to make Tasks, Events, and Notes and use the Daily, Monthly, and Future Logs, and Index. I actually think Rachel Miller's book “Dot Journaling” does a better job explaining it than Ryder himself does here.

If instead you want to read a self-help book that tells you a bunch different ways how starting a bullet journal is the key to a better life, then you'll like this book.
