Carrie, maybe it isn’t really about commitment? In a relationship, since you said you take it seriously and you made your mind up a long time ago to make it work, you have an end goal – you know what you want. But as far as a job goes, once boredom strikes or perhaps you’ve gained the experience you want, you move on. In other words you either found what you want and it isn’t all it was cracked up to be, so you move on. Or you realize whatever it is, you won’t find it there. Same with the house. If you think long enough about that idea you may discover that’s not what you really want. Or you get cold feet so to speak because that is a rather large undertaking and perhaps it just makes you nervous.
At any rate, to get back to the job, like curlymoe said,older generations did/do tend to stay in a work place longer because security was/is a big issue for people. Today with all of our touchy feely pop psychology we all seem to be looking for more!
Just my two cents worth. I too get bored once I’ve learned what I need to, can’t do the same thing twice either. But in terms of family, I value that so I also stick with my marriage. I think with anything, you have to know what it is you want, the end goal, and the decisions come much easier. Of course figuring that out isn’t so easy, I’m still working on that. How’s that for a motto – I know I want something just not sure what it is ?
