Doing nothing counts as not a thing and doing a thing counts as one thing, which is what it says it does.

It may have two dot points, but only one of them is something.

If I tell my wife I was busy all day because I was doing nothing, she would say you did not get one thing done today, and she would be right.

In the meantime, please feel free to explore the button at your own pace.
