I dislike making special trips to the ATM, and carrying around bucket loads of coins in my pockets., so I took the opposite approach.

I put my weekly expenses on a single credit card, with the caveat that I have to pay it off every week. I have a small savings account into which I set aside cash for fun things. If my weekly credit card bill is over the limit, I have to take the money out of my fun savings account, which I don't like doing, so I somehow mentally naturally find a way to spend less to avoid dipping into savings. It took me a few weeks to get used to it, and now it works great.

Another advantage s that my intermittent expenses which require a credit card, such as Lyft rides and refills on my pre-paid public transit card, now appear of the same credit card as my trips to Chipotle & Walgreens.
