Re: I feel like I've arrived, with the prime cards in my sock drawer :)
I've never really longed for a card, unless there was a bonus. I do have the Blue Cash Everyday, Discover More, and Citi Premier somewhere in the house; you aren't alone in not needing those issuers. I do use the Citi 5% on gasoline, drugstores, and groceries though. Most people only have a few cards for this very reason. You don't ever really use all of the cards you have(if you have a lot), and some people are bad at remember dates and such.
