If I had to give one piece of advice to a budding entrepreneur, I would say: 'Aim big.'

You need more than just a great idea. Your product or service must add an enormous amount of value to some industry. If the idea isn't completely new, it has to be better, cheaper, or more efficient than what we already have.

The factory model of education is a gargantuan bureaucracy. Some kids are good fits - I wasn't. The system gives you bad grades and tells you you're stupid. You don't think, 'If this kid's not a good fit, it could be the system's fault.'

I found school very boring and frustrating.

Los Angeles is a rich city; California is a rich state; the United States is a rich country. The money is out there, and Los Angeles teachers are demanding that it be spent where it belongs, on our kids.

Keynesian modelling relies on marginal propensity to consume and marginal propensity to invest. The idea that if we give more money to the poor, they have a propensity to consume that's much higher than the wealthy, though I wish they would talk to my wife about that; she seems to have a propensity to consume.

What I usually do is hoard money - I accumulate as much as possible in the fear of not having enough to pay tax.

People who are passionate about what they do reach financial comfort and wealth more often than those who are not. That argues for doing one of two things. Finding your passion and pursuing it. Or becoming passionate about what you're already pursuing.
