How can I spend less?
One things about psychology - people spend more money when its an abstract concept instead of having cold, hard cash. What does this mean? People spend more money when they use credit cards for day to day purchases. While I still use a credit card for day to day purchases, there's a big difference between bringing $200 to costco to pay for groceries and laying out 10 $20 bills vs swiping a card when you see a number flash on the screen. If you're truly looking to reduce expenses, keep this in mind.
