A short list of slow tools
Paper and a single pen. A kitchen timer with a mechanical bell. A book with a broken spine. Tea that has to cool before you can drink it.
Each one asks for the same thing: stay a little longer than is comfortable. None of them can be refreshed, none of them will interrupt, and none of them pretend to be urgent.
The list is short on purpose. The point of a slow tool is not what it does, but what it refuses to do.
