Over the years, one of my favorite pieces of advice to give to bankers when discussing ways of staying motivated in their jobs has been to remember that we are all working in temporary jobs. Lots of folks are a bit puzzled at first by that assertion.
I then point out that most of them had jobs before the ones they have now that were also temporary, whether they knew it or not. Temporary doesn't necessarily mean "short-term." But it does mean that it will eventually end.
