I purchased the eBook format and followed along just fine with the content. I found it to be engaging, providing examples that are not only actionable but also thought-provoking. The book offers a simple way of being productive without all the fluff associated with complex systems. For those who purchase the eBook, you will notice QR codes at the end of the book. I recommend using a separate device to scan them, or you can print them out. The choice is up to you.
This book has sections where you'll want to revisit, so I'll encourage you there. It's definitely not a one-and-done read for me.
