greetings from venezuela, this is a very personal opinion I have about investment and passive money, for some years I have the firm belief that it is a myth that "let the money work for you instead of you working for it", the reason for this is that money is earned (selling a product or providing a service) when you transform the money into a product you make it very prone to losses although I know it is a nice dream but reality shows that the rich have systems that collect money and then that money is jealously guarded as savings.
