I don't know how to become a billionaire but I do believe that the key to getting rich isn't rocket science but simple mathematics at least in the United States today. Don't live outside your means. Don't get in debt. Don't risk things you can't afford to lose. Everything else is compound interest and mathematics. "Whenever a really bright person who has a lot of money goes broke, it's because of leverage... It's almost impossible to go broke without borrowed money being in the equation. We should never risk something we have and need for something we don't need. You only have to get rich once." Edit: Sorry, I am completely wrong. That sounds reasonable in an equal society but what happens in an unequal society where the odds are stacked against you and you can't even save with a full-time job? What happens when you can't afford an education? What happens when you're run over by a car and can't afford your medical bills? When your job is outsourced to a third-world country? I unfortunately don't know the answer to that. I wish I knew.
