Carry An Envelope Everywhere
Bring a small envelope with you everywhere you go to keep your business cards and receipts stored safely. You want to do this so you can keep a paper trail. You never know when you need to deal with being charged twice for something on your credit card.
Most people toss receipts immediately these days. Don't be one of those people! Keep your receipts.
Have Automatic Savings
Set something up that will automatically send money from a portion of your cash into a savings account every month. You'll increase your savings over time. You will also have money for special events, like vacations or weddings.
Check If Your Debt Will Expire
If you've got debt, remember that it could expire. Talk with an expert and determine if your debt will expire after some time. If it's true, don't bother paying a nickel to the collections agency.
