Money can't buy you happiness, oh who are we kidding, yes it does

The Huffington Post recently published its findings that after a certain level of income per household, most people won't notice a difference in happiness. This means that if you live in California, for instance, once you hit the benchmark of $95,325, your happiness level won't change if the next year your household finally hits six figures. 

But what if your household hasn't reached the benchmark? Does this mean that you haven't reached your peak of happiness? Considering the high cost of living for some areas, that sounds about right. Or is happiness truly a state of mind?
