The major thing that holds you back when you're trying to change a bad habit like eating, smoking, or drinking too much is your belief you are out of control.

Who would you trust right now? Which bank would you trust? Which investment would you trust? Do you really want to put your money; do you want to suffer more of these losses that we just had? You know, these volatility that we see is just unexplainable by any rational standards. Nobody has any clue about how to explain this, and nobody wants to experience that.

So, I think people need to figure out quickly how to pay loans and how much cash they should really keep.
