My favorite career end that I'm naturally working towards to is the ability to jop hob to different roles without having prior experience. One way to do that is to be able to show in an interview that you have transferable skills and learn crazy fast. Another facet of that is that you need to identify companies that are open to this sort of thing.
Another career end is to become rich and not work. It's not achievable for everyone of course. But it is a type of career end.
Other career ends that one becomes disabled and live on disability checks or welfare. To me, it seems that this is a career end that people want to avoid.
I feel digital nomads aren't really represented in this career end. You could put it under independence, but the characterization of independence in this blog post was quite narrow which is why I feel the need to state it explicitly. Some people are in their career end when they can just work remote 4 days and have a decent salary.
There are many more career ends, what could you come up with?
