Washing dishes to wash dishes, not to get them done
Thich Nhat Hanh's most repeated example draws a distinction between doing a task in order to finish it and doing the task as the point of your attention while it's happening. Washing dishes while mentally rehearsing dessert treats the present minutes as an obstacle between you and the reward; washing dishes while actually attending to the water's warmth and the plate's weight treats those minutes as fully alive in their own right.
He extends this logic outward: if you can't wash dishes peacefully, you likely won't experience dessert peacefully either, since the mind that rushes through means will just as easily rush through ends, always reaching for the next thing. The habit of treating the present as merely instrumental — a means to some better future moment — is, in his account, the single biggest leak in most people's capacity for peace.
*Takeaway: pick one daily chore this week and do only that, with full attention, instead of doing it while planning what's next.
