Learn superior money formulas from others -- or develop them yourself

In my own case, my father once "played money" with me, showing me how to add and subtract money and exchange money for goods. It took about 15 minutes. Apart from that, I learned no money-expertise from my parents, or at school. Had I been more precocious, I would have carefully observed my parents' relationships with money, observed how they handled it... and learned to not make the same mistakes!
If you're not as wealthy as you'd like to be, then the first step is probably to suspect that you might have more to learn than you thought. Suppose we formulate a "unit of money-expertise" called the "gate" and to operate at the level of Bill Gates, you need to master 100 gates of money-expertise. So how many gates have you mastered?
Suppose you've learned how to pay for things you buy, count your change to see that it's correct, work at a job for a paycheck, bank the checks, withdraw money, write checks, pay bills, balance your checkbook, use a credit card, buy and sell stocks, file a tax return, etc. In other words, the things about money practically everyone knows. How many gates would you say your money-knowledge represents? Let me warn you that there's a common human illusion of thinking that you know more than you really do. I would estimate this basic money-knowledge at maybe one gate. But what if it's really a small fraction of a gate?
In any case, once you realize how little you really know, you can open the door to learning...
Personally, with all I've read, experienced, thought, and written about money, I've mastered maybe 3 - 4 gates! That should be enough to make millions!
The key to developing your own superior money formulas is study the successful money formulas of others, coupled with the realization that anything can be improved -- indefinitely!

Don't work for money; have money work for you

"Money is the seed of money, and the first guinea is sometimes more difficult to acquire than the second million." -- Jean Jacques Rousseau
The first lesson Kiyosaki emphasizes in Rich Dad, Poor Dad is that rich people don't work for money; they have their money work for them. Personally, I'm satisfied when my money earns a 10% return per month for me. If my money isn't providing this kind of return, I start looking elsewhere. For examples of how you too can achieve this kind of return, see Risk Meter.
Fortunately, you don't even need to have money in order to make money work for you. There are millions of people in the world with "surplus" money that's not being put to very good use. You can organize your money-making activities so that some of this OPM (other people's money) works for you. For a general approach to achieve this, see Zero-Risk Money-Making.
