That’s quite an interesting concept. Robert Kiyosaky talks about it as well. If you believe that rich people have become rich because they have committed fraud, they have deceived other people, they have exploited their workers and the like, you will never become rich, because your mental picture is that rich people are evil, and you don’t want to be evil, right?
Apart from that, I think the best advice, which I don’t follow, is to have a high savings rate. If you are able to save 80% of your income you will be financially free in 5 years. If you save 50% you will be in 14 years. 80% is not achievable by most people because paying bills and eating accounts for more than 20% of their income. 50% is achievable but depends also on your income and other factors. In most cases you have to have a present miser life to achieve future financial freedom.
The approach I take is to always spend less than I earn, and keep investing, so I’m richer every year and I know that I will have a financial stable future but I’m not obsessed with being financially free because for that I have to sacrifice the present to be so in the future, and at the end of the day, I don’t know if I will be dead in 15 years.
