Ask HN: What Skills/Skill Upgrades You're Getting in 2021?

Preferably something that can be measured with milestones (e.g.: foreign language exam, either you pass or you don't), "stretches your brain" in a different way (so if you already know Java, picking C# may not be that much of a stretch), and reasonably useful for your life (but not necessarily work). Mine so far: 1. Aiming to pass B2 exam for French (meets all 3 criteria above) 2. TLA+, hard to measure progress, stretches my brain in a different way, but practical utility is dubious 3. Category Theory, similar to TLA+, but even harder to find pragmatic applications. Am keen to hear from others.
