Avoid bad credit
First of all, the credit file you build will follow you for your whole life. That’s why it is important to develop good consumer habits from a young age.
Second, credit is essential for the purchase of high-priced goods. You will absolutely need to rely on credit for the purchase of a house. People who pay for their house in cash are very rare and in most cases extremely rich.
Third, if an important, unexpected cost happens to you and you do not have the means to cover this unexpected event with your savings, you might need to apply for credit. However, people who have bad credit are more limited in the amount given to them and are penalized with higher interest rates.
