These are not "books about purpose." Most books about purpose offer you someone else's answer and hope it fits. These six books do something different — they give you better questions, sharper tools, and deeper permission to find your own.
Each one was chosen because it connects directly to something you've done in this room. You'll recognise the ideas. You'll see the exercises. And you'll go further than Room Two could take you alone — because a book gives you hours of sustained immersion that no exercise or webpage can replicate.
You don't need to read all six. Start with the one that speaks to where you are right now. The others will wait.
