When you post something publicly, first rule of thumb is to never read the comments. Or just read the ones from people you know personally.
In many cases, the comments can be filled with people agreeing with the creator, the people who follow the creator, the people who would defend the creator.
If you're gunning to be a creator with an audience, I don't think the answer is to completely ignore your audience. It's to learn how to cultivate a target audience, how to not engage with malicious people, how to be strategic about your messaging, outreach, branding...
Of course, if you're not interested in those (truthfully tiring) things, then your rule of thumb is a pretty good one for most people.
The toughest thing was getting a reliable bit of time each day to sit down and do it. Routine, cajoling, and rewards were all involved. So was keeping it lighthearted; the kid has to be on board! Each lesson has straightforward exercises then a brief story, very short at first, longer later in the book. We'd do the exercises and one read of the story, then kid would read the story to my partner. We started in September, and I remember by Halloween the kid was reading candy wrappers. After finishing it, the next big thing was finding stories the kid genuinely liked to keep it going. Continuing to read together after the lessons ended helped: for a while, kids will keep running into lots of new exceptions to the usual rules, etc.
English spelling and pronunciation are a lot, and the book is also, implicitly, a catalog of the tricks English plays on kids and other learners. Part of the book uses a semi-phonetic alphabet where e.g. ee and sh/ch/th have distinct glyphs, but it all still looks enough like English that the jump to regular writing later in the book is doable for the kid. Even with that alphabet, the book has to teach common words like "is" and "was" as exceptions (with s sounding like z). Decades later one can forget little kids deal with all this and eventually handle it like second nature.
The book's originator thought that you could teach math with a broadly similar approach--breaking things down into very small steps and practicing them in isolation then in larger tasks--and doing that was part of his career, but I haven't found similar teach-your-kid book for arithmetic/basic math. If such a book did exist I'd've given it a try!
It's a (paid) online platform that breaks down mathematics (from 4th grade to university level) down into very small steps/skills, makes you drill them periodically, and also integrate them in increasingly advanced skills. The platform tracks your successes and failures to give you just the right amount of training at just the right time (in theory). You can see the exact skills they train as these really huge interconnected graphs, all created manually.
I read their pedagogy https://www.mathacademy.com/pedagogy and it seems to line up a lot with that philosophy. To use their language, they emphasize "finely-scaffolded steps" and "developing automaticity".
I always love to see more projects or initiatives in this area. I also know of https://physicsgraph.com that was inspired by it, but for physics.
