For me, it was that the Internet never forgets and that you should never enter your real name. In my opinion, both of these rules are now completely ignored.

I feel like a lot of small shops now (especially restaurants and convenience stores) charge for using a credit card in a manner that wipes out any benefit from “cash back rewards”.
To me the bigger benefit is that a card that is opened many years ago (pair on time) gets you a better credit score. This will net you much better deals throughout life for major purchases like a car or home (if you are lucky enough to still be able to afford one).
