Christ spent entire year experimenting with productivity.
Some of his productivity experiments included:
Meditating for 35 hours a week
Working 90 hour weeks
Waking up at 5:30 every morning to see impact on his productivity
Living in total isolation
In his book in each chapter he shares important takeaway from what he learned.
For example – everyone likes the idea of becoming more productive and making positive changes to his or her life.
But in practice both are tough and having a deep meaningful reason for becoming more productive will help you sustain your motivation in the long run.
Each chapter is also followed by a practical task in the end to encourage yourself to try in practice whats been covered in the chapter
