It's the same for almost any profession I think. As long as you can't decide what to do with your own time, and you work from the supervision of someone else, you will always feel like that. Maybe you are better off trying to create your own business instead.

Or become a freelancer, and switch jobs every two years or so. It isn't easy either way.

But there are other jobs where you would be a better fit, so I think you probably should switch jobs, and avoid the risk of getting burned out.

There where you are currently at, it's not going to get any better, right?
