Invest in a library card.
Then go read Tom Stanley's "Millionaire Next Door" and/or "The Millionaire Mind" followed by William Bernstein's "The Four Pillars of Investing" or Frank Armstrong's "The Informed Investor".
While you're finishing the books-- max out your 401(k) & IRA contributions, save at least 10% of your gross pay, and don't pay more for debt than you'd earn on savings. It's probably better to pay off the car loan but you'll know after you finish reading.
The book written on E-R.org, "The Military Guide to Financial Independence and Retirement", on sale now! For more info see "About Me" in my profile.
I don't spend much time here anymore, so please send me a PM. Thanks.
