It is another form of source of income that can really change your life. As others have said, no one gets rich working in offices unless you have a high salary there, but to us, we won't get rich because we need to invest in something. No matter how hard and rough you are going through, at the end of the road it will be fruitful. That is why right now people are really saving because they want to invest and take a risk on something as that is their chance to get rich.
The money that we can save must be invested so that it generates income, this is the basic rule of rich people. You can earn a lot, but you can't become free if your money doesn't work for you.
The bottom line seems very simple, but most people stop at the stage of saving, when at the end of the month we save some money and that's it. Sometimes people decide to invest their money in a bank at low interest rates and believe that this can bring them income, but in fact this is not even enough to cover the inflation rate. And so it never comes to real investment, because it looks very complicated for ordinary people.
