Manipulating currencies is when you're going into the marketplace and buying something in large amounts to depress the value of the currency.

Our plate is full. We have a lot to do building our company organically and that is our key focus.

Abenomics, quantitative easing, fiscal policy - we know all the issues.

The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that.
