Cook at home often: If both the husband and wife work, this is likely to be very difficult. Start out with the habit of cooking at home once a week and slowly increase the frequency until you find a balance between saving money and getting stressed out.

You don’t have to entirely ban drinking coffee, but skip it as often as possible unless you make it at home.
