I've spent eighteen years failing to stay in one kind of library. Academic stacks, a regional department managing forty-five branches and eleven mobile libraries, a science observatory's reading room, and, for a while, the library of a wine farm, built essentially from scratch, tailor-made catalogue and all.
Somewhere in there I also built a library, unpaid, for a technical high school that didn't have one, because it needed doing and nobody else was going to. I've taught information literacy to students who'd never used a database and to wine producers who just wanted to find last year's rainfall report. I hold a Master's in Information Technology, I'm slowly finishing a PhD I started because I couldn't leave a good research question alone, and I speak English and Afrikaans fluently enough to argue in either.
I've also relocated internationally more than once in the middle of all this, which is its own story. What hasn't moved is the actual work: making a library function properly with whatever budget, staff, and chaos it's actually been handed, not the version in the textbook.
