Everyone has made financial decisions, even since someone started getting to know money. A child who is given pocket money, for example, has been given the freedom to buy food he likes or to save money. So, financial decisions are not related to a person's age. What matters is whether the financial decision is correct, wise, and beneficial to the breaker.
There are several factors that should be considered before making a decision. First, decisions must be part of achieving financial goals. The simplest, for example, is the decision to eat at a restaurant. Eating is part of consumptive needs. In financial planning, of course there is an allocation of how much of your income to meet consumptive needs. Now, when you decide to eat at a fancy restaurant, you must make sure that this action does not damage the budget allocation that has been prepared.
Impact Second, financial decisions must look at short, medium, or long term impacts. Suppose you don't have a house and still live in a rented house. On the other hand, the rent for the rented house is quite large. Then the question may arise, whether to continue to contract, while waiting for an increase in income and one day you can afford to buy a house, or right now you are planning to buy a house with a bank loan.
Third, financial decisions must have a background. Every financial decision should be based on a background where the rationality can be justified. So, none of your expenses are "like".
Financial decisions are actually an important element in determining whether you will succeed or fail in managing finances and in turn achieving financial goals. Decisions that are reactive or without planning will usually have more negative impacts.
