Live on less than one income.

 If you are a two income family stash away the entire 2nd check! By taking a serious look at your total take home pay for a month you can get a true reality check of how big you should be living. Sit down with paper and make a fake life living off of 75% of your income and see where you would cut back your choices. You never know when one spouse will lose a job, so live on only one income now while you can to save the rest.
