+1 on Ask Dad videos - this is a good channel: youtube.com/@dadhowdoi

Also +1 on everything else you said, especially the never stop learning point.

OP, it’s totally ok not to know things - you can seek them out in advance, or you can discover them along the way, as and when necessary.

You’ll be ok, pretty much everyone muddles through life one way or another. Best of luck 👍
