The best way to pull back from encroaching burnout is to step away, reflect, do something enjoyable, and talk to someone who cares.
Really the only tip I could ever give someone at this point is to pull away, reflect, do something you like, and talk to a human who cares about your current spiraling.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

Loved Xteink
I recently got an Xteink and it is a really cute little e-reader device! I thought I'd try hacking around on it, and it's been fun to tweak.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
