Software engineering just comes really easily to my brain, somehow. Most of these days is spent designing, architecturing and managing various things, it takes time, but in the end of the day I don't feel like "Ugh I just wanna sleep and die" probably ever. Maybe when we've spent 10+ hours trying to bring back a platform after production downtime, but a regular day? My brain is as fine as ever when I come back home.

Contrast that with working as a out-call nurse, which isn't just physically taxing as you need to actually use your body multiple times per day for various things, but people (especially when you visit them in their homes, seemingly) can be really mean, weird and just draining on you. Not to mention when people get seriously hurt, and you need to be strong when they're screaming of pain, and finally when people die, even strangers, just is really taxing no matter what methods you use for trying to come back from that.

It's just really hard for me to complain about software development and how taxing it can be, when my life experience put me through so much before I even got to be a professional developer.

Have you done physical labour? I find it odd you think physical labor cannot be as mentally taxing. Having done some myself, I agree with GP.
