I keep getting asked, over and over, what is the single best frugal tactic. Considering so many different lifestyles and needs, there are countless ways to save money and one of them may be the best for you while it won't work at all for someone else.
BUT... since when did I let impossibilities stop me?
Here's what I think is the absolute best tactic ever: Do nothing. Absolutely nothing. Don't go shopping. Don't go anywhere. Don't turn on the TV or snack or do anything to run up your water bill.
In other words, don't consume anything.
I don't mean that you should sit staring out into space with an empty tummy and an empty head. Have a meal, but make it simple and inexpensive. Borrow a book from the library and read. Go outside and watch the birds, the traffic... watch the grass grow. Just don't consume anything that costs money.
Try it. You might actually like it.
