I used to save like a maniac when me and the wife were just me and the girlfriend. But times moves on and you get married and buy a house and a second car and have a baby and pay for childcare (which is bleeding me dry, it's like a second mortgage) and I've seen my savings slowly wither away into pretty much nothing
We're quite fortunate in that both our parents are pretty well off so if the worst happened we'd have support behind us for a while, but day-to-day that doesn't offer much consolation when I can't buy that new pair of shoes for a month or two or we can't afford to go to Peppa Pig World with the sprog.
I mean don't get me wrong, we're not poor and live in a nice new house and generally can afford what we need (but not always what we
want) but we feel the strain all the same. It's tough being a grown up, particularly if you're trying to remain as debt-free as you can, it'd be so easy to just get a couple of high-limit credit cards and hammer them to improve our lifestyle, but eventually that debt would ruin our lives so it's not something we consider doing (we do have a credit card, but it's not used regularly).
I also echo the posts earlier in this thread saying that school/college/uni woefully underprepares kids for modern finance issues. I've never used a protractor in my life!
