I retired just over 3 years ago. when I retired, I got a lump sum and decided to manage my own retirement money. In preparation, I read about 8 financial books. Admittedly, I did start to gravitate towards one type of investing........index funds.
Best Book: Coffeehouse Investor by Bill Schultheis. Investing your retirement money CAN be simplified. I found this book to be simple, short, easy to read, sometimes funny, and made sense to me.
Most Boring Book: Four Pillars of Investing..... fell asleep dozens of times, could not get past page 100. Sorry, I don't think investing needs to be this complex. This book is great for insomnia, however.
