Small tools I keep coming back to

The tools that survive in my life are rarely the ones with the most features. They are the ones that open quickly, do one thing, and do not ask to be managed.

A plain text file is the first. It has no schema and no sync service. It works in every editor I have ever used, and it will still open in twenty years. Most of my notes are just lines in a file, separated by dates.

A kitchen timer is the second. It is not a productivity system. It is a way to decide how long to stay with a task before standing up. The physical dial is the feature: there is no notification center to get lost in.

A camera with one lens is the third. A fixed focal length is a constraint, and the constraint is useful. You stop thinking about which lens to use and start thinking about where to stand.

The pattern is the same each time. A small tool leaves room for attention. The best ones disappear while you use them.
