Every mens magazine has proven with SEVERAL tests that you can really get by with just your IDs, bank card, and if you carry a gun on you, a CWL. Transit ticket if you use public transport like a train or bus.
Even the busiest and biggest spending individuals have been tested and shown that throughout their day, they don't even need an ID card on them, but it's just smart to always have it on you if something were to happen. Tests have shown most people can go through the WHOLE DAY carrying JUST a debit or credit card, and most of the time don't even get ID'd. They've also shown that the only reason most people go into their wallet is to grab that debit card, or in some cases if ID'd, the ID. All other things were just excess baggage.
Women have even adapted at carrying less with a purse. Have you seen how small some purses are? If a woman can minimize, surely a guy can slim down the wallet.
I'll use your wallet, not you per say, but your wallet as an example. Leave the cards you don't use at home. The cards you don't use, you're likely at home when you plan to go to the places associated with them anyways, so put them somewhere secure, or in a drawer.
You ALWAYS have your wallet on you, are you going to Blockbuster EVERY TIME you go out? Library? Grocery store (don't those usually have keychain versions anyways?)? Best buy? Bass Pro?
Right in your own list, you can eliminate ATLEAST 3 cards (monthly ones) right off the bat.
Blockbuster, they can look you up in the computer if you go there before you get a chance to go home.
Library, they too can look you up if you go unexpectedly. That's probably the most useless of cards to carry because that's probably the LEAST visited places of all the cards you carry with you.
Insurance card, health insurance? OK, that one is plausible, but car insurance? Why not leave that in your glovebox? When do you ever need to use it when NOT in your car?
Do you really need to carry TWO credit cards? One for emergencies, sure, but wtf is the other one for? If that one gets declined? Emergency of an emergency? Leave it at home in a safe.
It's not "getting by", it's carrying lightly/smartly and NOT carrying what you DON'T need. What if you lost your wallet? You'd be SOL cause you have no IDs, no credit cards, and all your other cards are gone to boot. That's A LOT of calling to do when you get home. Not to mention, every time you sit down, you sit on a 3 inch brick. I used to carry a HUGE wallet, and after carrying minimal, I've never looked back.
