Like many, I didn't choose my career. It sneaked up on me. And I actually like it. The money is ok, the work and the people are interesting, and gosh, I do get lots of cool toys to play with.
A lot of people are dead set on the actual kind of work they're doing and they fail to realize that there is more to engineering and science than just the design or the research. You have to sell it, maintain it, document it, market it, finance it, and manage it.
And surprisingly that involves a lot of other people. You could be doing very interesting work but everyone around you are scum of the Earth and you would be unappreciated. You could be doing some work that is almost as interesting, but have some interesting people, a stable job, less stress, and a better life overall.
This is not just about the work. This is about building a career and living better. I don't need to work on the really cool stuff. Sometimes the mundane stuff can be surprisingly fun and surprisingly challenging.
