Life & Work by Ray Dalio.
Book #10 provides life principles that others can implement in their own personal and business routine.
I took a different approach with book #10. Instead of buying a physical book, I decided to go with an audio book to enjoy the 2 hr. commute to and from work. With an approximate 16.5 hours of material, finishing the audio book took around 3 weeks, since I replayed some tracks.
Honestly, there is so much valuable information, I definitely need to go through it a couple of times to absorb it. Lucky for us, Ray Dalio has created a mini-series of around 30 minutes (28:46 minutes to be exact).
Keep growing, keep investing.
