- Empathy, sympathy, and a willingness to see other points of view. Not politics per se, but just asking "what does $PERSON feel right now? why?" on the regular
- Communication skills -- too many to list, but uber-critical for most jobs / relationships / contexts. Only 10% of my job is actual tech; 90% is communication
- Cooking -- you're gonna have to eat for the rest of your life, so get some basic skills
- Basic understanding of cars -- still going to be a thing for the forseeable future and worth knowing a little bit about
- Basic understanding of computers -- like cars, this is a tech that's going to define your life, likely for the foreseeable future. Most of HN are tech focused, but if you're not, understand it as much as possible
- Basic understanding of housing tasks -- too many skills to list, but you're gonna have to live somewhere as a renter or owner for the rest of your natural life, so learn a bit about how your plumbing, electrical, drainage, etc. works.
- Basic finance -- you're gonna have to buy shit for the rest of your life. Understand how mortgages, credit cards, interest, inflation, etc. works. Learn enough to be confident and skeptical, since there is a lot of snake oil and obfuscation here.
- Make something with your hands -- candles, woodworking, cooking, welding, pottery, whatever.
- Something physical -- sports, gyms, running, even if just long walks with the dog. Take a weightlift course, or do some soccer training clinics, or just read a runner's mag sometimes, whatever.
