Like many before us, we will now attempt the 7-Day Money Fast. You really need to be ready to plan for this one.
1. Same rules apply as for the 24-hour fast, only times 7.
2. If your city does not yet have a SmartCard or pass system for subways and buses, you will need to find out the least expensive and most efficient way to package tokens or cards for the week.
3. Make sure to have a full tank of gas before your fast starts.
4. Ditto an entire week's groceries, every single meal and beverage and snack.
It's a little disingenuous to call this a fast, as you will almost certainly spend some money you can't anticipate. But you might be amazed how many incidental expenses drop away once you get in the habit of thinking ahead.
As with the 24-hour fast, log every expenditure and savings, as much as possible, and send yourself, your card company, or the charity of your choice a fat check at the end.
