I followed these guys on the Morningstar chat boards for years. They are full of practical wisdom, not fluff. Moreover any person can get their insights for free (just find them with a google search). I highly recommend, especially for a younger person just starting out. Early investing unleashes the powerful phenomenon of compounding. You need about 20 years to start witnessing the amazing and wild—in a good way—aspects of the compounding process. Keep reading, learning and buying and yes, get this book (borrow at a library if possible; invest the money you would have saved). Keep buying no matter what. When market conditions are scary buy more! S&P 500 index is a solid default choice, but there are many other great ones. Just keep buying and never look back!
