Actually is not only a book, is a series of books, written by a guy, Kyosaki. The first book I suggest you to read is “Rich dad, poor dad”. Is written like for IQ80 people, but is very useful.
Basically, we, humans, we were used with some habits from the industrial era. Our parents were brainwashing us: “Mom, go to school, get high grades, be nice, go higher somewhere with a big paycheck. This is how success will look like.”
WE WERE STUPID!!!! WE ARE SLAVES.
Imagine that one day you are loosing the capacity to work. Statistically speaking, wortldwide, not only in states, employees have money reserve for 3 months (or something). Some live form paycheck to another, some have higher reserves. But the average is aprox 3 months. After that you need help (from the state, from family…) You become a burden.
In the same situations are the freelancers and the company owners. If the become incapacitate, the have money for a specific time frame, afterwords they are in deep shit.
The idea is that all three categories above are exchanging time for money.
In order to earn more, you need to sell more of your time. Get another job, make another surgery, craft more objects to sell. And this is not wise, because, TIME is limited. You only have 24 hours. You can, at some point to charge more for your time, but this is limited.
You should sell your money, not your time. This way u will have more free time and you can make money even when you are asleep. You should become investor in something. In a patent, in a franchise business. You should spend money on thinkgs that will provide u FUTURE SOURCES OF INCOME. The rest are pure expenses.
WAKE UP. Try to make money from something that are not time dependent. Otherwise u will be a slave for ever!!!
