A significant part of being an engineer is solving the problem you are asked to solve. No doubt there are lots of other problems. There are frustrations but these are probably not the problem you have been asked to solve.

I feel this is often missing in how people talk about their job these days.

You also don't have to work there, really, if it gets to that.

The vast majority of people have no equity in their employer. That is not a valid requirement for doing your job.

The majority of people 'just work here'. Having equity is not the norm.

I do just work there and that’s okay with me.
