Most of the "lessons" are not groundbreaking, they are rather things that are obvious and most of us know about. The value for me came from having them all written down in an organized way. It's much easier to refer to something more tangible than your memory.
One thing that bugs me and puts me off is the financial literacy that Troy mentions. I try to translate some terms to my mother tongue only to find that, even then, I still don't really understand them.
Does anyone has any pointers on how you can start improving on this like finances 101 or something?
