I look at frugality as a series of scaling down. You don't have to go from spendthrift to tightwad in one fell swoop.
Identify where you are, and experiment with doing one level less.
Take your typical Friday movie night:
- Watch a DVD with takeout instead of dinner and the theater.
- Substitute a frozen pizza and ice cream; try Netflix.
- Use a premade dough with your own pizza toppings; watch a movie from the library.
- Try making your own pizza from scratch; make a family movie for the grandparents.
Or do as we've done, and move Movie Night to Monday.
