What is something you learned (or had to re-learn) in 2025? New skills, insights, life lessons that could be worth sharing with the rest of the forum.

For me: I've been forced to relearn how important sleep hygiene is and that it is something that can fall away slowly resulting in misery. Maintaining a consistent be time is a chore but one that does make for a happier life.

I started learning Rust more actively and then WebAssembly, via building https://github.com/agis/wadec.

I plan to continue doing that in 2026.

I learned to write my own WebSocket library more than 2 years ago. Last year I learned to write a web server that did HTTP and streamed redirection from the same ports as WebSockets. This past year I learned to do everything else, like all the OS related things, in my personal app:
