Deciding whether to stick to being a web developer, or switch to something else

(thinking more like rocket software, or something with security (but maybe sticking with web), or some other cool sh#t

I don't know yet, what I do know is even when I'm creating an erp system, I find it very unsatisfying

"I helped create the software on that rocket"
Or
"that hospital uses the system I've helped to create"

Sounds a lot more satisfying than,
"that company uses my 'warehouse resources manager'/'webshop'/'planning system'

But then again I don't know, I now have a stable job, know what to do and know the language we use.
