Credit score is hilarious. Until I was like 30 I paid for literally everything with cash. Everything. Never missed a bill. My credit report/score came back "unreportable." Not a shred of data to go off of. I was unable to obtain any credit card. I ultimately had to go to a bank and place $1500 in what was basically a 0% CD for the duration of my credit card, with the agreement my bank would just take it if I didn't pay. After a couple of years of paying that religiously they allowed me to unsecure the funds, but I still had shitty credit afterwards.
