The better things getter, the more we tend to expect things to get even better.
Hence begins the long walk down the road toward entitlement. It seems to be a first-world problem for the most part. We expect more because we’re special (or so we tell ourself).
I think the key is to find contentment, real contentment, with where you are and what you have. Never let the fire inside of you die of complacency, but don’t mistake complacency for being thankful with the good stuff you have now.
It’s a delicate balance and one that far too often we fall afoul of.
