Thank you, love to see high-quality comments like this. I would recommend to anyone interested in investing long term to read "investing for adults". It's a 4 part mini-book series 150 or so pages each, and out of the hundreds of investing books I've read (I do this for a living at a firm, I don't recommend anyone read that many investing books XD) it is easily one of the best.
The amazon link above, but for kindle, the series is only like $10. It really goes over some important concepts that most asset managers would learn for their clients. Save yourself that 1% a year commission from an advisor (it adds up) by learning what they learn. But so far you seem to have a great understanding of healthy financial practices.
