Q: What's the hardest thing about being frugal?
A: I'm generally pretty cheerful about frugality--it's just plain fun for me to save money! At this point in our marriage, though, the hardest thing is staying frugal when we no longer have to scrimp. This is the first year that we've had a true abundance of income, relative to our lifestyle. There is always the tendency to make life a little easier, to spend more freely, to upgrade. But if we don't remain true to our goals, our lifestyle will quickly outpace our income. Staying frugal is what keeps us in abundance. When I think about your question in those terms, it doesn't sound hard at all.
What about you? What do you find most difficult about pursuing frugality?
