How Money is Annoying

What bothers me about going from overspending to spending just what we have, is "saving" money doesn't feel like "saving" money.

For example, I was planning to buy a mattress. It was about $250. I got Grandpa's spare bedroom mattress instead. This should, in my eyes, mean I have an extra $250 lying around. But it doesn't! It's just $250 that I didn't have that I didn't spend, so instead of being -$250 I am still at $0.

That's not fair!
