Reminiscences of a Stock Operator by Edwin Lefèvre

This is an old book. I did not realize how old it was until I started reading. That being said, I believe it is timeless and still 100% relevant to today.  I would recommend this book to anyone who has even the slightest interest in any high-risk investments or markets.  However, if you don't have the time for a whole book (just do audio book because everyone has time for that) the take home message is: Get smart, put in the long hours of studying, and once you know your stuff, don't be swayed by rumors, tips, or your idiot brain. Keep cool and rely only on your smarts and your numbers.
