Despite what books, TV ads, financial planners, and others would have you believe, there is no big 'secret' to being financially successful. There are, of course, lots of tax loopholes, complicated investment methods, and other such tricks to making money.
Unless you are a CPA, tax lawyer, investment banker or otherwise want to be involved in studying the myriad financial laws of this country (and possibly others, as well), a simpler approach probably sounds good to you.
