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.
