<prompt> Human: hey everyone! thanks for all the help youve been, both to me, and everyone else here!i have a question i seem to see a lot of opinion around lately. do you prefer to pay in plastic credit cards or paper cash? lately i have been paying with my card. but i have noticed, unfortunately, out of sight out of mind. so i sat down and used an online aggregate tool to sort through my expenses. often i still have a hard time remembering where i spend a lot of my money every month.isnt cash a simpler, less abstract way of representing money? my fiance and i had talked about keeping jars aside in our house as a budgeting scheme, such as keeping one for each of restaurants, going out with friends, and groceries, just to name a few.that way well never use too much money, because once the jar is empty, thats it. what do you think? can paper ever be king again?  <response>: I hate getting a handful of change back and having to deal with it. That plus cash back rewards plus much easier budgeting via Mint has led me to use credit cards for basically everything.
