Dollars And Sense explains why it's so hard to manage money and teaches you how to combat false cues and natural desires so you can reach your financial goals.

Many of us like to think that we're good with money.

We might budget, save, and invest. But a lot of the time we spend with our heart more often than our brain.

When dealing with money, humans are 'predictably irrational.'

Driving a little out of the way for a better deal when we need to gas up our car seems pretty common sense.

That's not worth the extra time and effort.

We like to think that we're getting the best deal, but we've got to be realistic about what a real 'good deal' is.
