I don't know what the difference between an investor and an ordinary person is. I only know the thinking of an investor that they are always looking for ways to make their investment profitable because I am also an investor. and ordinary people I don't know what they think.
I think we are having a misconception here about these ordinary people. They can also invest, but unlike investors, they are more focussed on investing time, attention and sometimes money rather than most of the investors that also use time and most of the time money to maximize profit.
