My Grandma Tucker used to have an envelope system for budgeting. She kept money and coupons together and at times held the envelopes together in her pocketbook with thick rubber bands.
My Grandma Tucker worked in a hardware store. She understood 4 key rules about money:
Rule 1 - Give every dollar a job
Rule 2 - Save for a rainy day
Rule 3 - Roll with the punches
Rule 4 - Stop living paycheck to paycheck (live on last month's income)
