7-day challenge

Follow the tasks at your own pace. Tick a day after trying its task or an accessible alternative. You can pause and return; seven days of practice do not guarantee a lasting habit. Reflections can stay in your head or on paper — nothing is sent.

Start with the first task below. Tick it after trying it.

Next task: Day 1 — Notice & choose

Notice the lighting in one room. Identify one light that can be switched off when the room is empty and safe.
