Replying to "Postmortems Help Address Causes of Errors" [Dface]

I’m going to write about the following paragraph:

First question:

I think I have this problem. Like I think I know about a lot of errors. It seems like so many that I don’t know which ones to work on. It’s kinda hard to know which are good errors to work on. I don’t know if I have the same problem of not having time to postmortem them all. I think it makes sense that I don’t have enough time to postmortem them all cuz it’s so many. I could work on one error or another and I could keep going but I don’t know if I can get to them all. It seems like a lot of work.

Would finding about your errors be like that you see you made an error while typing? What if you mistyped a letter going 80 wpm that got you to miss 100% accuracy? Is that an error? What if you make many errors while trying to type 100+ words a minute. Are those errors? Are those from overly ambitious goals? I think you could make so many errors in a scenario where you’re doing something really hard. You could be overwhelmed by them. Is that what finding the errors and not having time to postmortem them all means?

What if I’m writing for CF, what would an error look like there? Idk I don’t really look too much for errors to postmortem here. I think I find something I could improve and I work on that. It’s hard to think of errors I did that I tried to improve. I wonder if that’s a problem. How do I know if I really fixed the underlying cause? Did I move on too quickly?
