Ask yourself whether you have earned the right to have an opinion. Opinions are easy to produce, so bad ones abound. Knowing that you don't know something is nearly as valuable as knowing it. The worst situation is thinking you know something when you don't.

By and large, life will give you what you deserve and it doesn't give a damn what you like. So it is up to you to take full responsibility to connect what you want with what you need to do to get it, and then to do those things.

The best advice I can give you is to ask yourself what do you want, then ask 'what is true' - and then ask yourself 'what should be done about it.' I believe that if you do this you will move much faster towards what you want to get out of life than if you don't!

I think the greatest tragedy of mankind is that people have ideas and opinions in their heads but don't have a process for properly examining these ideas to find out what's true. That creates a world of distortions.

Demand is best measured in terms of spending. You know, I think in traditional economics, it's a mistake to measure it in terms of the quantity of goods.

When two intelligent parties disagree, that's when the potential for learning and moving ahead begins.

An economy is not a complicated thing; it just has a lot of moving parts.
