The most important point in financial management is being able to strike a balance between expenses and income, most people don't care about the amount of spending so that every month they run a deficit, they do it by borrowing which actually makes finances more difficult, stop spending that is not important.
we have different financial management. there are people who take the money they work hard to fulfill their daily needs without thinking about future needs and there are some people who take the results of their hard work to buy production goods that can generate other income such as buying cars to rent and building shops to rent and so on. etc.
