Oh, you haven't seen the half of it yet!

Wait until you spend 10 years in the cube farm and actually get nothing useful out the door at all in all that time! Sounds impossible to believe, but you'd be surprised at how much of a typical desk engineers effort in a big company will just go to waste.
I have a "dead projects list", it's orders of magnitude bigger than projects that have seen the light of day.
But it doesn't have to be like that, there are infinite options. The key is not to worry about that sort of stuff, just do what you enjoy, have a laugh, and work on your own projects outside of work if work isn't as satisfying as you'd like.
Everyone is looking for the "perfect job", and it essentially does not exist.
I've liked most of my jobs in one way or another, and took the good with the bad. But would I have done them if I didn't need to put food on the table? - no way.
If it's any consolation, there is very limited scope in physics compared to engineering.
Take Phil in my most recent video. Got his PhD in laser physics but had to work in retail for a while looking for a job. Never found a job in physics, and realised they didn't exist, unless he went back to uni to teach it, so went back to study and is now a Patent Attorney.
Electronics Engineering is not destined to be a Dilbert Cubicle Farm dwelling job. If you don't want to design electronics everyday then don't.
Want to get out and see the world?, no problem, plenty of jobs that offer that. A colleague of mine spent 6 months flying over NZ in a helicopter for an airbourne mapping company.
I've worked in the geophysics industry and could have taken my job anywhere if I desired. Survey boat in the middle of the North Atlantic? - no problem.
I almost applied for a job at the Square Kilometer Array a few months back, would have been typical boring big project work, but the application and project are incredibly cool.
Stick with engineering, there are countless options available to you. Physics will be very limiting.
