That's the rub, isn't it. Financial literacy is as contentious a field as nutrition is[1]. I recently got Tony Robbins' Money: Master the Game [2]. It claims to use both common sense principles and tips from investment masters, and ultimately settles upon pretty reasonable ideas (such as choosing index funds and avoiding mutual funds). Sure, he might be a motivational speaker- but he echoes advice from people in the know, right? Turns out some online investment bloggers do recommend it [3], while others don't [4]. Still others have created a three-hour podcast critiquing it [5].

At some point, one just gives up looking for the best class to take and settles on whatever comes along. To his credit, Robbins did teach me that investment advisors are not to be trusted to keep your best interests in mind- what you should be looking for is a fiduciary.
