None of us always make the best financial decisions.

We need to believe that we're good people, and we'll do just about anything to maintain that perception.

It was shocking to realize how many low-income Americans don't have savings accounts.

That’s a lesson we can all learn: the more we have, the more we want. And the only cure is to break the cycle of relativity.

The bad news is that ignoring the performance of people is almost as bad as shredding their effort in front of their eyes. Ignoring gets you a whole way out there.

Imagine you have six loans, small to huge. People want to close loans and because of that, they try to pay off the small loans, but that's not the right strategy. The right strategy, of course, is to pay the loan with the highest interest rate. People make this mistake and it costs them lots and lots of money, it's a very expensive mistake because interest rates accumulate and become very, very expensive very quickly.
