Fidelity has a great tool that maps out where your money goes and compares it to how much you make.
Once you can track where your money is going you can start cutting back where you need to. Maybe be aware of the overage on your cell phone bill and save that $30 every month.

The Golden Rule of personal finance is to pay yourself first. Put $50 a month into your savings account before starting to pay your bills.
