[Guardrails: a system designed to keep vehicles from straying into dangerous or off-limit areas.]

They're everywhere, but they don't really get much attention . . . until somebody hits one. And then, more often that not, it is a lifesaver.

Your finances. Your marriage.

Maybe your greatest regret could have been avoided if you had established guardrails. In this 4-part series we challenge you to stop flirting with disaster and establish some personal guardrails.
