I am tired

The mirror replied "To whom?"

"The miller who made the flour for my bread," the queen would say, or "Whoever spun the thread my shawl was made of".

The second time, she says "To the King," and she is pleased to see herself once more.

The third time, she says "To the Royal Advisor," and is once more satisfied to see herself.

The fourth time, she says "To the scribe who takes the King's letters." She is shown the man's wife. And she seethes, but quiets herself, for it is only right that a man loves his wife.

The fifth time, she says "To the Court Wizard," and is shown the man's departed mother as he remembers her from his youth, radiant and smiling and warm and larger than life.

The tenth time, she says "To the Stable Master," and is shown the fastest horse in the stable, majestic and free as the wind even in captivity

"To the baker," she is shown the man's daughter, young and adorable and full of joy and laughter.

"To the artist who did my portrait," she is shown a painting of a woman done by the man's teacher, who he still looks up to now that he is well established himself.

"To the Royal Knight," she is surprised but not displeased to see the castle's entire guard force in the middle of doing drills.

The one hundredth time she asks the mirror, and it asks her "to whom?" she once again says, "To me." And she does the same the one hundred and second, and again and again and again.

Writing 和風細雨 (he2feng1xi4yu3; gentle breeze and light rain) with a cat's tail on a water-writing mat.

Water-writing mats turn black when wet and return to their original colour once dry, so they are often used to practise calligraphy with water. The black colour allows you to see your writing clearly, and the mat can be reused as soon as the writing dries and disappears.

kyoshi: sometimes some murder is OK

kuruk: just punch people that disagree with you

Roku regretted not killing Sozin specifically because it gave him the opportunity to come back and kill him, then the Air Nomads. His lack of decisive action led to a lot of tragedy, and so his advice was to make sure whatever he did, make sure it was permanent, or Ozai would come back.

Kyoshi regretted not moving sooner on the threat of Shin the Conqueror and waiting until he was at the very edge of Kyoshi Peninsula before actually doing anything. She allowed a lot of destruction on the continent because she didn't move fast enough. Her advice is to move swiftly instead of allowing Ozai more time to act.

Kuruk basically did nothing as Avatar by his own admission and basically just said that Aang had to do something, and not to back off of his responsibilities because it was hard.

Yangchen is complicated because, well, she isn't talking about one of her own regrets. She's the one trying to give the 'Violence is sometimes necessary' talk to Aang, because she's the best person to tell him his duties as Avatar have to outweigh his duties as an Airbender. Arguably she is the one telling him to murder Ozai, but personally I read that as more 'you need to do what's right for the world, and I am giving you permission to break our cultural rules to do that. Because I am the only person you can ask for absolution.'

And they agree that yes, they do know how to eat, in theory. The problem is the watermelon. Surely, if they figured out where to start, they'd figure out how to do it, but they have no clue how to get started with it.

This goes back and forth. No, it's not an emotional issue, they're not afraid of the watermelon. They can eat any other fruit, other sweet things, and other watery things ("it's watery?" they ask you). Is it the colour? Do they have a problem eating things that are green on the outside and red on the inside?

"It's red on the inside?"

Wait, they've never seen the inside? At this point you have to ask them how, exactly, they eat the watermelon. So to demonstrate, they take a whole, round, uncut watermelon, and try to bite straight into it. Even if they could bite through the crust, there's no way to get human jaws around it.

"Oh, you're supposed to cut it first. You cut the crust open and only chew through the insides."

And they had no idea. All their life this person has had no idea how to eat a watermelon, despite of being told again and again and again that it's easy, it's ridiculous to struggle with something so simple, there's no way that someone just can't eat a watermelon, how can you even mange to be bad at something as fucking simple as eating watermelon.

https://drmaciver.substack.com/p/how-to-do-everything had a nice list of additional examples like this, with (non-)obvious major insights with regard to opening stitched bags, cleaning your bathroom floor, using a search engine, catching a ball, pinging somebody, proving a theorem, playing sudoku, passing as “normal”, improving your writing, generating novel ideas, and solving your problem.

If you’d asked me six months ago how to get better at something, I’d probably have pointed you to how to do hard things. I still think this is a good approach and you should do it, but I now think it’s the wrong starting point and I’ve been undervaluing small insights. [...]

Every time he tells me this story, his frustration by this point in the story, years later, is evident. He still sounds frustrated by it, despite all the time that passed. Teachers had been giving him crap for years because he hadn't been making much progress with the instrument.

When he got to the private instructor, she acknowledged his frustration, and asked him to try to play for her. He did, and she saw all he was doing. She then did something no one else had done before. She asked him to put his mouthpiece on a different clarinet and try to play the same notes. Like magic, it worked. She looked at the clarinet he had been using and found that the school's clarinet needed it's pads replaced.

He went from last chair to first chair nearly overnight, having been taught far more techniques than typically taught at that age just to overcome the broken instrument preventing him from making noise.
