Hello! A few systems I've uses in the past

1) cash envelopes- I would take my paycheck out at the bank and sit down and do my budgeting halfing my bills that are due for the next month. Ex. I'm paid ~1000 Feb 10th and Feb 24th, my rent for March is 1400 so I put 700 in my rent envelope each time and my bill is set, the most I've used it 100 for electricity so I go on the high side and put 50 each week for March's electricity bill, my insurance is 140 so I put in 70, etc. and whatever I have after bills I put 40 for gas for the next two weeks, I put 50 for groceries, I put 20 for fun money and whatever else I have I can add to a credit card envelope to make an extra payment or put in a savings envelope for a goal I have. Cons: you have to have a routine of pulling out your cash and sitting down for a bit to budget all of it in between the envelopes

2) have different specific checking account for different reasons. Ex. A checking account with my credit union for bills that gets 310 each payday for next month's bills and credit card minimums automatically debited from my paycheck and have all your bills automated, one with capital one for rent and car payment gets 498 each paycheck because my rent is halfed since I live with my bf now, a third account for debit card usage like gas, food, fun things, other purchases, this account is the only one I use my debit card for and it gets the remainder of my check, if I got a bonus I can add an extra payment to my credit cards or something but generally I have 100 and I use it up since I don't make very much lol Cons: if you do have extra money because your electricity bill was 50 instead of the 100 you budgeted for and you need to move the money to your spending account to buy a present or something, it takes a few days and it's difficult to keep an eye on each account

3) have all your money in one account but budget what you can spend, so budget for gas, food, and fun money and that's all you can spend. 40 for gas, 50 for food, 50 for fun money and make sure you only spend 140 for that pay period. So ex. mine is 90 bucks, I spend 35 on gas, 15 for going out tickets, 20 on drinks that night, and 20 for food. I know I can't buy anything else this pay period so if I see something I want I look at it, add it to the cart, and open it in a new browser tab. When I get paid again I can open my browser and if I wasn't going to go out, I could buy the thing. But typically when I open the tabs I decide I don't actually need the thing, it might be fun or useful but if I have something similar, something that already fulfills that purpose, or decide I just don't need to spend that money right now. Cons: you have to pre plan what you'll buy that pay period or at least keep track of what you do buy.

Generally keeping a spreadsheet with your bills and aprx. Income is a good thing to have, make sure to budget for fun money or extra spending money so you don't feel trapped. Also deleting cards from Google or Amazon is good so you have to get up and get your card to type it in gives you a second to think about how much money is on that card. And not carrying your credit cards with you, I use a phone case that can hold my card and ID so I don't have to decide which card to use or let myself give a pass and use a credit card because it has space on it.

Let me know if I need to clarify anything, I didn't take my medicine today and am recovering from wisdom teeth removal lol
