One of the best ways to save a hell of a lot of money is to just sit down and trawl through your monthly expenses. Look at every single expense and try to eliminate it or at least reduce the cost.
For example, if there a cable TV charge, see if you can haggle them down or switch to a lower plan. Check for any binge spending and wipe that out!
The key here is to really spend some time on this task. If you can’t complete it in one sitting, that’s fine. But once you finish, you’ll be feeling a lot better. The spend planner from mint.com is also really useful for keeping track and optimizing all your income & expenses.
