Part 3 - Productivity
Productivity is downstream of well-being. The reason Part 1 (Physical Well-being) and Part 2 (Mental & Emotional Well-being) came before this part is that nothing in this part really works without the foundation those parts build. Trying to be productive while exhausted, anxious, ill-rested, overcaffeinated, or weighed down by unprocessed emotional material is a losing game. The techniques don't compensate for any of that. Take care of the body and the mind first, and most of the rest gets easier.
The second piece of the foundation is doing work you actually love. If you spend your days forcing yourself through tasks you fundamentally don't want to be doing, no productivity tool in the world is going to fix that. The first chapter of this part addresses this directly because it's the most important productivity question there is.
Productivity, in the way this book uses the word, is about spending less of your day on friction and noise so that more of it goes to work that actually matters to you. The practices below are about clearing space instead of filling it.
