I think it’s probably true that people are never satisfied with what they have. They always want something more or something different from what is theirs. This just seems to be part of our human nature. Look at a toddler, Give her a toy to play with and she’ happy—until she sees something else. Then she wants that other toy to play with. If she and her brother are each given a cookie, she’ll look to see whose cookie is bigger. She’ll protest loudly if she thinks her brother is getting more.
“The grass is always greener” is an old expression, but it’s a good expression of how many of us feel. We’re always striving for a better job, a nicer place to live, a fancier car, or more expensive clothes. Part of this reaching for more and better is because we care about what other people think and want to impress them. Part of it is trying to make ourselves feel successful. But there’ also something in our nature that tells us we can do better and reach higher.
This isn’t always a negative quality. There’s another saying: ”A man’s reach should excess his grasp. Or what’s a heaven for?” It’s a good thing to be constantly pushing ourselves and looking for something different. If we don’t try for more and different things, we begin to stagnate, like a pool that doesn’t get any fresh water.
The problem comes when we won’t let ourselves be satisfied with anything we have. If we have a comfortable life and still feel as if something ‘s missing, then we need to look inward. The something that’s missing may be in our spirit.
