Problem: You set a goal to spend less money over the course of a year. Which measurement strategy will best help you track and achieve your goal? Compare the number of things you buy each month with the number you bought in the prior month. Keep track of everything you spend money on in a spreadsheet. At the end of the year, organize the items by cost. Use an app to track your monthly cash flow. Compare each month's outflow to the prior month's outflow. Compare your bank account balance at the end of the year to the balance from the beginning of the year.
