What else should I read and learn besides economics and finance to invest wisely? I would say Psychology books!
It's common to think that the failure of many investments is solely due to a lack of competence--
"we didn't conduct thorough research, chose the wrong industry, or entered the market at the wrong time..." However, after reading Daniel Kahneman's "Thinking, Fast and Slow," I've come to realize that psychological factors play a significant role.
For instance, we would rather hold onto losing stocks and sell the winners prematurely because we feel the pain of losses more acutely than the joy of gains(Loss Aversion). We will be tempted to enter in bull market and believe the stock prices will continue to rise because we anchor our estimations to recent figures (Anchoring)-similar to how we might be persuaded to buy a plastic bag for $100 if the store originally priced it at $100 and hundreds of people purchased it at that price.
FIRE is a life style, other than simply personal finance. If you want to understand the fundamentals of decision making, I really think this book is a good start. I've also written a review briefly explaining these concepts plus some others, if you don't have time to read the full book:
