Gone is the day where you work at a job for thirty years and retire. Millennials jump around and switch careers. I think it's important for CEOs to highlight career mobility within a company, so that employees don't get bored and continue to be stimulated.

One of the best ways to convince someone is to use a telling example, a story, a narrative. When Steve Jobs announced a new product, he told a story, exzlaining how a product would change the world as we know it. He turned Apple into a story whose challenges and adventures you want to hear about.

Researchers have found that identical twins who have been separated for long periods of time actually invest in a similar manner. Biology really does affect how we spend money.

The oldest and most important currency is debt.

In essence, money gives us the calories we need to survive. Over time, we became aware that exchange and cooperation increase our chances for survival. Eventually we create tools to facilitate trade. One of these tools is called money.

Money is becoming increasingly plastic and digital. If there is a major disaster, let's say an asteroid strike, we'll go back to trading meats and furs. We won't need an abstraction, a dollar bill, but real tangible goods to survive.

We are privileged that the dollar is the "currency of last resort" and the most important currency in the world. Global commodities are priced in dollars. Central banks in other countries hold great quantities of dollars. The dollar was the safe harbor, the port in the storm during the credit crisis.
