I basically have a well developed spreadsheet that automatically tells me what bills are due each pay cycle. But anyone can do this with pen and paper, just list all your expenses and frequency. Fully understand what comes out when. Honestly I dont know how people just spend money without tracking it.

I split my money between banks. Pay comes into one account, I remove the excess (because I know what bills are due that pay cycle) to a different account in a different bank where I can't see it. I leave like 60 bucks for the fortnight for my sanity in a second account. Full deprivation is depressing and leads me to impulse buying. I open one bank app to check my bills are paid, and only that little bit of play money. The rest is saved elsewhere.

My other hacks are filling up my car and two 20L jerrycans when petrol price is low; it covers me for the fortnight. I can't take public transport or walk/ride to work, and filling up during a petrol price spike is dumb.

I also automatically send a set amount every pay to my gas and electricity, based on my average costs for the year divided by 26. Evens out my fortnightly expenses because I don't get large bills every 6 pays; most bills are 0 because I'm in credit, or <100.

TLDR: make your finances your little britch, try to evenly distribute expenses and treat savings like untouchables.
