>>96765864Your dad was right, however -
>>96765884My personal advice would be to get a credit card with a small spending limit - IE $1000 or under, and use that credit card to ONLY buy gasoline for your car (or if you don't have a car, find another regular small expense to dedicate towards it).
Make a payment on the card every month so the balance (and therefore interest payments) stay very low. This will help build and keep your credit high long term without incurring any substantial debt.
