There are two kinds of people:
1. Those who tell their money where to go.
2. Those who wonder where it went.
I write out the checks the day before payday and mail them after we make a deposit.
I have a spending plan, so I know how much I need to have in the account for groceries, etc.
The first check I write is a tithe check to my church. (Put God first.)
The second is to savings. (Save for a rainy day.)
The rest are written according to my spending plan.
To quote Debt Proof Living, make a plan, then live the plan!
