how can you be confident that anything supplied here will be retained if you were previously unaware you even needed to know in the first place?

The information I’m looking for wasn’t immediately important for me to know earlier in life, and because of a mix of the ADHD issues, a lack of home economics-type education and a lot of these kinds of responsibilities being handled by someone else growing up, I wasn’t really in a place to think of educating myself for the future. This all changed a while ago and I realized I needed to do a lot of catching up to be a functional, self-autonomous person. I’ve gotten the impression that there are a ton of folks who feel this way about stuff like learning to do taxes.

TL;DR, my brain holds it as useful, very important information now.
