Use a 3-bucket budget
Bucket 1 is fixed essentials (rent, utilities, insurance). Bucket 2 is goals (debt, savings). Bucket 3 is flexible life spending.
This format protects priorities without requiring detailed line-item accounting.
Make your plan survivable
Set realistic numbers based on what you've actually spent in the last 30 to 60 days.
If your budget assumes perfect behavior, you'll likely abandon it after one rough week.
Common failure pattern
People overspend one category, feel like they failed, then abandon the whole plan.
Better move: cap the damage, rebalance one category, and continue.
