I Will Teach You to Be Rich

I appreciate that, despite the hacky title, this book is quite literally the opposite of a “get rich quick” scheme. Gives very specific practical advice about all the aspects of personal finance: picking good checking and savings accounts, good credit cards and the importance of paying them off every month, taking full advantage of your company's 401(k), setting up a personal Roth IRA and contributing a hundred or 2 to it every month so later in life its compounded interest will be huge, and how (and why) to diversify your investments and minimize fees, taxes and penalties on them. Definitely recommend to all 20-somethings.
