What skill did you learn during lockdown that is still helpful to you now?

I learned how many times I can jerk off in a day. The pandemic was hard for us single folk.
- Hard and soft. Alternatingly.
- How many?
  
  It was about 6 before I hit a psychological wall and didn't want to do it anymore that day.

Nothing. Lockdown was the moment everyone else started living the way I pretty much already did.
- Hey me too! I had friends and family asking me how I got through the days and now we all read a lot and have many plants.

I can cut my own hair now, it's great. Not only the money, but the convenience of getting a touch up whenever I want is great.

I learned how to grow mushrooms and now I always have an ample supply.
- I've been thinking about giving this a go. Any resources you recommend to start out with?
  
  Mostly from Reddit unfortunately. I actually miss those communities. Uncle Ben’s tech is the method I started with. You might find some YouTube videos with that search, but I’m almost positive there is still the uncle Ben’s subreddit. You also need to find a spore supplier, of course I found mine through Reddit.

I learned to stop caring so much about work. I slam my laptop shut with a vengeance at 5PM, earlier if I feel like I can get away with it.

Learned how to become a "home barista". Instead of popping a pod in my Nespresso machine I grind my own beans and brew my own coffee fresh, every morning.
- I can do decent espresso art now which I'm pretty chuffed about.
  
  I never attempted latte art, probably because the only milk foamer I have is the one that came with my newspaper machine

I learned to repair a carburator for a vintage motorcycle with my dad. I bought the bike with the carburator in a box for $300. I probably put around $500 more into it of which new tires cost around $200.
That was more than 3 years ago and still ride it today. I've done done some maintenance work myself, like changing the oil, brake pads and fluid, and other minor things.
- Bringing life to something old always gives so much joy..

Made some progress towards Spanish fluency. Still not fully fluent, but went up a CEFR level.

I learned how to move the ship backwards by alternating harpoon pulls.
This was before I realized that you could turn the ship using only the wheel even when you had no forward momentum.
But still, I felt like a genius the first time I backed the brigantine out of a dead end.
- You sound like an old timey whaler and it's very pleasing. Not the implications for the whales. Just the old timey sea-ness.

Hiding alcohol from my girlfriend and family.
- Wanna start a business? Vodka that comes in what looks like a 24 pack of Poland springs?
- That's not good mate, please get some help
  
  It was a joke about dystopic pandemic days, and thank you for your reasonable concern. We have this worked out.

I learned to let go, I used to have a hard time removing people from my life, now I don't care

I learned approximately 100 ways to cheat in online exams or exercises, even if they make you share your screen or have camera enabled, which has been immensely useful to me for reasons I do not need to explain...

Disciplined working from home. Some people seem incapable of it, either due to distraction or at the other end of the spectrum, overworking themselves.
I allow some flexibility for errands and appointments, but I start and finish at the same time every day and take my lunch at the same time.
- I'm one of those who can't. Temptation to nap is too strong. Also I have that procrastination issue where I'd rather be cleaning the floor with a toothbrush than do work, so it's hard not to do housechores when I hit a wall in my day.
  On top of that, I need more face-to-face socialization. I just do. I need to go somewhere that's not my house every day or I spiral and it's not pretty.

How to quit an 'essential' job without any advanced notice and move 300 miles.
Okay, putting away the snarky attitude.
Resume and interviewing skills in my specific career. Pleasantly surprised with the job offers I got during the pandemic.

I like to think I've gotten better at my music production skills. Not useful necessarily, but enjoyable.

I learned to play guitar which was fun I guess
- It does seem extremely fun, i always wanted to learn bass but was always so scared to ask my parents..
  
  It's never too late. A lot of good songs can be played on bass without being too difficult if you enjoy pop

I didn't get a day off the whole time, but sourdough. Starter's still alive, but I don't make it very often these days.

Financial stuff. IRA, 401K, individual stock, bonds, CDs. Iz gonna help me make muulla

Calisthenics to build strength without access to a gym
Brewing great coffee
Interviewing skills, that landed me a >100% raise
The most sustainable method of weight management for me so far

Most of the people on this planet are assholes.
- How does that answer this question in any way?
