My parents taught me that debt was bad. They told me that credit cards were traps to get you into debt, that preyed on poor impulse control, and that it was better not to have one. If you can't tell, my parents grew up in a time when the credit score system didn't really matter, and didn't understand it.
I did not get a credit card. I did not have any loans, for school or anything else.
My credit score wasn't even a number, it just didn't exist. Even the bank I banked with, which could see that I had more than $8k USD deposited monthly, that could see I had $30k in an account with them, would not give me a loan to buy a car.
Even if I were to get a credit card and pay it back on time, my credit score would be quite low due to having no history, and I still could not get a loan.
I'm fortunate that the apartments I have rented so far have not done credit checks, only background checks and looked at salaries / offer letters, but there are many apartments I simply could not rent since I would obviously fail their credit check, despite never having had any debt.
