Financially, I am on a spending diet for the month of September. That means that when the kids want to go to McDonald's, I tell them we will go in October. Same thing for clothes, or house stuff, or anything that is not required and available from the grocery store. The reason for this is that I am committed to paying off my credit card debt as soon as humanly possible, and one month intervals are workable for me.
Setting small goals can make big, depressing and overwhelming tasks bearable. Taking it day by day, week by week, or month by month can get you there!
