I think many of us have been living close to the edge in our earlier years.
The only difference, we learned we didn't like that feeling...and we did something about it.
This is true.
To me, it's a bit of a double edged sword. I could never going back to living hand to mouth, I hated it too much. That's not to say that unfortunate circumstances might take be back there some day... but let's set that aside for a moment.
I've found myself becoming a bit neurotic about money. Though I'm far from the most frugal soul and some of my spending habits would have some of our more proficient TAs shaking their heads, I have find myself being unable to stop worrying about money and just live in the moment. I'm too wrapped up in the 'destination', there is no 'journey'. When I spend money, instead of enjoying it, I feel guilty.
Recently I started spending too much money on week to week living expenses. Sadly, I didn't enjoy any of it and I felt a bit like an anorexic would after an evening of binge eating. I've tried to pull myself up on it and am spending less, but I've just gone back to obsessing about the 'destination'.
Then I kick myself for caring so much about money and think to myself 'wow, how shallow are you, you can't even enjoy life because you're too preoccupied with money'.
So, sometimes, when I see someone with only $10 to their name until their next pay cheque, I think 'I'm glad I'm not in that situation', especially if the person is in a miserable headspace. But then I see other people with $10 until payday who live (seemingly) much more rich and fulfilling lives than me. They live in the moment and seem so much happier.
Anyway, I don't think you need to spend money to be happy, but it's hard to be happy when you can't even eat out without thinking 'this accounts for x% of our monthly budget'.
I know it's about moderation, but evidently I'm prone to extremes.
