This book, which started out as a four-page letter to my three adult sons, shows how a simple and mindless approach to 401k investing can make every one of you a multi-millionaire before your 60 years old. While most of us aspire to get their 401k balance to the point where you can say F*ck You to your boss and job and just bounce, you must also build your 401k to the point where you can F*ck Off for the rest of your life. It's easy, and it's the most wonderful place to be. So invest an hour of your time to read it. You'll thank me later.
