Money is just a number in a database.
Well yeah, "money is just number". As in this quote above. Money is only a number, but, it depends on how many numbers do you have. It is only a number, but those numbers will define what and who you are.
Moreover, right now, the digitalization of the money has been developing in almost every country. We only have numbers on the database, but we do not hold all of that money in our hands. We don't know whether the money is real nor not. But, we have the numbers that can be used for everything suitable.
..But from what I've noticed, most people don't keep track of how much money they have, how much they're spending and how much they need...
In my opinion, it will depend on each person. Well, probably most of them do that thing. But for those who have lots of money, they will absolutely use the financial consultant to manage the income and outcome of running the money. Of course, how we manage will determine how many numbers we have right now and in the future.
