What's something surprisingly easy?

Building software from source. It depends on the program, of course, but most of the time it's quick and easy. Just download a folder, type in a couple commands, and you're done.

This has almost never been my experience.
Much more often, different versions of software dependencies, operating system differences, artifacts left by other software/previous versions, etc, result in mysterious errors. 5 hours of rabbitholes later, I find a comment on github explaining that x broke y and they'll fix it in the next release... 7 years ago. At which point I throw my computer out the window and leave to live the rest of my life in the forest.
- That sounds frustrating. I'm sorry.
I recall it being hard 10-15 years ago. Maybe I was just a young little linux n00b and I've gotten better but it doesn't seem hard now

Changing a car tire. I've changed bike tires and that's actually harder

Making your own bread. I always thought it was complicated and time consuming but t's really dead simple. It's just flour, water, yeast and salt, plus I add a little sugar to get the yeast going. Only takes about 10 minutes of actual work. The rest of the time is just the dough rising and baking. So you do have to be around but you're mostly not soing anything. If you want to try it google "no knead bread" and watch one of the many videos. In doing it for a couple years I've found that kneading the dough for a minute between the two rise times makes it poof up more, Before eggs got expensive a loaf cost about $1.10 to make, now it's more like $1.50, still way better than what you buy at the store for 2-3x that.

Weight gain. You think you're not eating more then you put pants on and BAM don't do up

I'd always thought that making friends and talking to strangers was super hard. My whole life, I've struggled along with just a couple friends...

Recently I've been reshaping my life and have been trying to make new friends... I'm still working on the execution, but just talking to people and finding common ground and being social has become SO much easier than I always thought it was. I think the trick was to just stop caring what people thought about me and being proud to be my genuine self.

There's a group I've been meeting up with regularly and we're going to the zoo this Sunday, and bowling next Sunday, on top of our usually scheduled Thursday afternoon general social meetups :)

Another thing that helps is being an adult. Most people develop their social anxiety during their school years, where they are forced into an institution with a bunch of little psychopaths and never get the chance to reinvent themselves or meet completely new social groups.
Once you graduate high school, most people are much more mature, you can choose where and when to meet people so that they will likely align with your values and interests, and if you don't like a particular social group or they don't like you, you can just try out other ones.
- Schools are hell, it's borderline child abuse with the social conditions
What helped reshape your life? Books, therapy, something else? Asking for a friend.:)
Well done, btw.
- Sheer will completely of my own volition, and some revelations that were sort of always there, but I finally grasped what was going on. Basically it boils down to for the last 20 years, I've been using romantic partners as a constant crutch to satisfy my social needs. My most recent breakup a couple months back had me really reflect on the past, and I realized that right now I need real true social connections, and don't really need any romantic physical connection. I was in a situation I'd never really found myself in before (alone, basically, not looking to date), and I just started throwing myself at situations, meeting people, being super open and vulnerable, etc...
  We ended up rescheduling the zoo, but we're still going eventually... I was super ready and down to go, but I guess everyone else was a little too eager when discussing it originally and didn't think about several things people already had on their calendars lol.

Switching to FOSS

syncthing, my beloved
- I have been experimenting with it recently. What is your use case?

Cooking - You can pretty much learn by trial and error. Or watch some YouTube videos.

I learned from meal boxes.

OP’s mum (someone had to say it)

Me. I'm surprisingly easy.

Easy like Sunday mornin

Not being an asshole. Like you don't need to be nice, you don't need to bend over backwards or go out of your way, just simply don't be a jerk to people. It's easy and free.

I couldn't agree more! This includes online
idk if i could say this is surprisingly easy or even really easy at all. this has actually been one of the most difficult things i've worked towards accomplishing during my life
at least, this has been really difficult for me online; i think it's much easier in person to not be a dick lol
but if it's hard for me online, maybe it's hard for folks in-person, too

Making someone's day. All it really takes is a small unexpected gesture. You pick up a little extra something for a coworker at the coffee shop. You let someone with small kids move ahead of you in the line.

Heck, even asking a favour of someone can be all it takes sometimes. If they're feeling ignored or in a funk for whatever reason, it brings them back and can be a little self esteem boost knowing they helped you out.

This is a lovely one! Come hang out at !wholesome@reddthat.com

Growing summer squash. I bought one tiny plant and stuck it in the garden bed, then absolutely neglected it for weeks. And now I have more squash than I know what to do with!

100 sit-ups, 100 push-ups, 100 squats, and a 6.2-mile (10-km) run, performed every day.

I think you're meant to be on linked in
What's so funny is I remember an old animation about Naruto fans saying they believed they could run at the speed of light if they did 500 pushups, 500 pull ups, 1000 jumping jacks, and 1000 leg kicks. I think it pre dated one punch man. But the joke was so similar. And I can't find that video anymore. It was an ancient flash video.
- Haha, it's a one punch man reference.
With no A/C of course.

mnemonism, like learning to memorise a deck of cards

I mean retaining the concept of a bunch of rectangular sheets of paper barely counts as mnemonism.
- Come on, mate. It's not just a bunch, it's fifty-two fucking cards. Complete with its own arbitrary monarchal form of government. Who is the fucking Jack of England? Of Thailand? It's got its own base-14 (seriously, fuckers?) numerical system where one isn't one but some other fucking word that escapes me, and is higher than the rest of the fucking cards. And don't get me started about the suits. I'll grant you hearts, but why are clovers not green but black and called something else? Why are diamonds red? Rubies are right fucking there! And why are shovels called not called shovels? Call a spade a spade!
  It's god damn near impossible.
- heh
