An investor, thinks well of how he can do passive income, he's not only depending on his fix income, but he's not wasting his time having a passive income, while a common man, most of the time, only thinks of how he will get a job, and don't care much on having a passive income.
But, a common man cannot become an investor without looking for that job. Let's take for example bitcoin investment now, I chose this investment and made some investment in it because I had savings from the job that I have worked for. It has been my desire to be an investors, but the opportunity did not come, because you cannot become an investor without money, so it was when I started saving up from my job money that I really made a very good investment in bitcoin.
We can only talk of a common man that would rather prefer to buy games and gadgets and making no investment move but not on a job because manner would not come from heaven. It is something that we all have to work for first and get the money for the investment.
