The list you keep yourself

Why this is the end of the section

Every published list is a copy, and yours is a copy of one of those. It is furthest from the source, nobody refreshes it, and it is the one you reach for when something has already gone wrong.

All the analysis in this section is only worth anything if it ends here, because this is the object that decides whether a reader ever collects the benefit of plurality at all.

The four ways it decays

1. It shrinks. One entry gets pruned after a quiet evening, then another, and nobody decided to hold one address.
2. It mangles. Line breaks are lost, two entries merge, a character is dropped in a copy of a copy.
3. It becomes unreachable. It is on a device you do not have, in an application that will not open, or behind something you cannot get to at that moment.
4. It becomes unpasteable. A screenshot is a fine record and a useless one, because it cannot be pasted and retyping is where errors come from.

What keeping it properly means

• Plain text, all three entries, one per line, in a place you can open quickly.
• Copied with the buttons rather than read across and typed.
• Kept whole. A quiet route stays in the file, for the reasons in quiet and then back.
• Refreshed occasionally at a calm moment, not urgently at a bad one.

The test that tells you where you stand

Without looking anything up, could you produce all three strings in under thirty seconds, as text, ready to paste. That is the only question in this study, and the answer is either yes or the whole set is theoretical.

A reader who answers no is not holding a set of three. They are holding one address and a memory that others exist.

Why the moment of use is always a bad moment

You never need the second address on a calm afternoon. You need it when the first one did not open and something is waiting, which is the state described in choosing in a hurry.

A store that is fiddly to reach is a store that will not be reached, because the fiddliness lands exactly when patience is lowest.

Refreshing without a channel

Nothing will tell you when to refresh, as nothing announces it explains. So refreshing has to be attached to something else: a moment when you happen to be reading about the subject anyway, with nothing broken.

Comparing your copy against a source at such a moment costs seconds and is the only maintenance available.

What not to do

Do not edit a stored string character by character if it looks wrong. Replace the whole entry from a fresh copy. Partial correction is how a nearly right string becomes a permanently wrong one, and it is closely related to characters from two addresses.

The whole section in one line

Other people's lists are objects to be read carefully. Your own is an object to be maintained, and it is the only one that will be in your hands when it counts.

What good looks like, concretely

Three lines of plain text, one string per line, in a file or note you can open in a couple of taps without unlocking anything unusual. Copied with the buttons rather than typed. Never edited in place.

That is the entire specification and it takes under a minute to satisfy. The reason this study is long is not that the task is complicated. It is that the task is so small that readers do not believe it is the thing standing between them and every benefit described on this site.

If you do one thing after reading any page here, it should be that, and it should be now rather than at the moment you next need it.

What this study is not. It is not advice about any particular application or device, and nothing here recommends software.
