Well certainly not the career aptitude testing in high school, which put me in ministry (the religious kind), philosophy, or military.
I was a cashier at a bunch of places and kept ending up working in the back office, then developing ways to do the bookkeeping on the computer (this was so long ago they were using paper ledgers). I did accounting systems for years, but doing accounting now, with coworkers I like.
I would not call it a passion but an aptitude. And as my former boss says - so much better to have a job you don’t love with great coworkers, than a job you enjoy with people you don’t.
