What if you want the world to be demonstrably better, and yet you're pretty sure the world is not just you?

Does that count, or is it axiomatic that for every person, the world is entirely just them and they have no concept of everything/anything outside themselves? I feel like this is probably only some people, and doesn't describe literally every person.

I don't think you read what I said.

I retired from industry to teach high school.

A really big part of why I did this is because I wanted to help. I make basically nothing. There are many more personally lucrative things that I could do that help society and people less.

But there's millions of ways that I could help. I didn't maximize my impact, I don't think. I did one that was a confluence between altruism, feeling good to me, conferring other advantages, etc. In other words, altruism was not the sole factor in my decision -- just a very large one.
