Ask HN: What did you learn in 2025?

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.

I actually don't want to have a job ever again. I love my new situation and business too much.

I learned if we show a little gratitude for the things or events happening around us, it makes our mind calmer.
