Why can't I move my body unless everything is perfect first?

You have made moving your body into a large event. An event needs a stage — the right clothes, the right time, a special room with machines. So the event never starts, because life rarely offers a stage. But walking to the kitchen is movement. Standing up from a chair is movement. Stretching your arms while water boils for tea is movement. You already move all day. The gym is not the only door into the body — it is only one door, and you have locked all the others waiting for that one. This is not laziness. It is a belief, quietly held, that movement does not count unless it looks a certain way. We can look at that belief together, gently, the way you would look at a pot before deciding it needs washing.
