It's all too easy to fritter away discretionary funds. However, setting up automatic payroll deductions can keep your income from being applied to your biggest expense: your wish list. Instead, consider setting up a payroll deduction to fund a savings or retirement account.
If your employer doesn't offer this service, or if you're self-employed, you can set up an automatic transfer to move money into a savings account and pay it just as you would a recurring bill. And if you've been known to pirate your savings accounts for one expense and then wish you hadn't, consider setting up separate savings accounts for vacation, holiday, medical, car repair or other savings [source: Mueller]. In just a month or two, you won't even miss the deductions, and you'll have increasingly robust savings to boot.
