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.
making an emergency fund is also very important.
It helps maintain the habit of saving and one keeps a balance between expense and income. I started making an emergency fund very late. But since I tried I am very happy
