Assuming not passwords. Things like name, address, passport number, etc.
I've had a few experiences waking up at 5 AM (in our time it's when the US has peak traffic and most issues arise) checking alarms and having to fix large systems on my own. This has left some non-negligible PTSD. I often wake up in semi-panic in the wee hours and check my phone for system status. It gets quite exhausting.
How do you deal with this?
I enjoy the feeling when I learn about some cool concept, when I engineer a robust system for production, when I learn about the nitty-gritty of some interesting implementation detail, when my dev process just feels really solid and frictionless, when I read the next Go changelog, when I read about some intricate hardware details, when I understand some apparently complex tech so well everything just feels more relaxed, etc.
What is it that "we" like? How do you answer when someone asks "what do you like?" and you want to explain something similar to the feelings above?
(In my case it also applies not just for tech stuff, but nearly anything that's new and perhaps uncommon information. I love learning and discovering. Everything from art history to reading some medical handbook about caring for pressure ulcers in elderly patients)
