I have the same problem in controlling the budget, the problem is also in my country here that prices are unstable and constantly rising, so you have to adjust your budget all the time to match the price differences.

The best way to control the budget is to have multiple sources of income, as you must have more than one source of income, otherwise you will be in big trouble if an emergency occurs and your income stops.

The other thing is that you have to control expenses, you must control your monthly expenses and give up some unnecessary luxuries so that your expenses match your income and the rise in prices, otherwise you may have to borrow, and if the debt accumulates, you are in big trouble.
