The only practice the book ever asks for, and the only one I'll push: ten minutes tomorrow morning that belong entirely to you. Kettle on, sit by a window, no phone, no plan. Be at the start of your own day before you hand it to everybody else.
That's it. That's the whole of the practice. There isn't any more.
Use this thread to say how it went — including the mornings it didn't happen, which is most mornings for most people. No homework, no streaks, no guilt. Just what you noticed.
