Some goals may have to be postponed temporarily. Take a lunch from home instead of buying it. If you have trimmed your flexible expenses as much as you think you can, check your fixed expenses. Maybe you can make some sizeable reductions here. Reduce utility costs by adjusting thermostats.
Housing is a big item in a budget.
Perhaps you should consider lower-priced housing or renting out a room. Perhaps it would be better to trade an expensive car for a cheaper one until you get caught up with expenses. If, after cutting your expenses as much as possible, your plan still requires more money than you make, you may want to consider ways of increasing your income. if you are both working, you might think about looking for better-paying jobs. In extreme cases, a part-time second job may be the answer. If either of you are not working now, you might consider becoming a dual-income family, or you might be able to make some hobby or talent pay off.
