Doing one thing by thinking about the next, and then judging each other because we are not focused enough: this movement can add tension to an already busy day. The book links attention to body presence and how to carry out the most ordinary gestures.
The proposal is not to force concentration. It is a question of observing dispersion, then slowly returning to what we do. This exploration concerns our way of paying attention; it does not pretend to explain physical or persistent fatigue alone.
