I've noticed I'll do everything I can not to spend the cash I've squirreled away for my 'rainy' day or for 'mad' money. Something about seeing that cold hard cash -- 20s, 50s, the occasional 100 dollar bill -- keeps it 'hands off.' When I do rifle through the stash, the low bills are the first to go.
Whereas I make the occasional dip into checking and even savings when things come up -- I had the pleasure of replacing the clothes dryer and the vacuum cleaner just the other week, for instance -- my cash box remains largely untouched. (Should you be looking for it, it's a small wooden box with the brass engraving 'I Love You Amy' that came from Excy with long-ago eaten chocolates inside).
Perhaps I should consign myself to become one of those 'ole Pioneer types who preferred to stash their cash in the mattress rather than in banks and investments. (I'd save money that way, apparently. In the bed-frame, I mean).
After I began to write about this, I read of this very phenomenon a few weeks ago in Real Simple. There was an '09 study prefaced where people in an experiment tended to hang onto larger bills than the 5s, 10s and 20s.
When people receive a substantial note they subconsciously realize that once they start using it, it will go away quickly. Spending smaller amounts on impulse items like candy or a Starbucks beverage, was much easier. Since I don't have the money to invest in gold or bitcoms (which sounded pretty useless from the get-go), I guess I'll stick to my system and hope for the best.
