Anyone else just not career oriented and stuck?

I hated school, just didn’t want to be there, felt like it encroached on ‘my’ time. Ended up getting graduate and post graduate degrees, despite that.

Then came work. And it feels the same. Never had a job I loved, even after 30 years of working, and never been particularly ambitious.

Doesn’t help that the only two jobs I ever wanted were Jedi Knight and Astronaut. So I ended up not ‘picking’ anything and kind of just fell into what was available (what someone would hire me for).

Have a nice middle class job, making a nice middle class (well, no thanks to inflation) income, but never going to ‘be someone’ in my field. In fact, I’m older than average for the job that I do, my team mates are all millennials.

Contrast this with my (younger) sibling who is on track to run one of the biggest companies in the world. (Does make me feel something of a failure at times.)

Of late I’ve been liking work less and less (if that’s even possible) and I’m not sure what to do. I could apply for jobs the next step up, but I know I’d put about the same amount of effort into that as I do now - I just don’t care? I’m going to age out at this rate, sooner rather than later, and I really don’t know what my next step should be.

I can’t afford not to work. 30 years of slacking off at work hasn’t been kind to my retirement prospects, but the idea of another 20 years of this is really depressing me.

Not sure what I’m asking here, maybe I just needed a rant.

Edit/Update: thank you all for your responses and kindness, it’s heartwarming to see I’m not alone.
