A lot of young people say: “I am a businessman.” But this is an empty statement because this noun is not backed by any actions; they have no business and they have no money as a result. A driver who does not drive is a pedestrian even if he has a driving license. A sales clerk who does not sell goods is a buyer.
In my book, I am only presenting grammar, that is, the backbone on which you can correctly build the flesh of the events of your life. This is a certain sequence of actions required for success.
