Of course I choose money, because money can also be used as power.
Money is power only if you know how to use it correctly. For example, the banks.
A promissory note that you sign when you get a loan is a negotiable instrument. It's like a check or money order.
The banks understand this, but won't accept your promissory note (money) as prepayment for your loan... which it really is. Instead, they make you pay your loan back a second, third, and fourth time (including interest) over a period of 5 to 30 years. They never return the value of your promissory note, even if they return the cancelled note.
Now, there is real power in money. And you won't even learn enough law to stand up to them in court.
