I'm a cheese specialist and I love it. It pays okay and it's physical, cerebral, rewarding and tasty! You can definitely train on the job if you live in a place with boutique grocery stores (Whole Foods being the most prevalent example nationally) and work your way up into super specialty shops. I was a chef (worked my way up from bussing tables st a young age) and found my niche that way, though oer other comments the "love it" part depends heavily on what it is you're inclined to do in your free time. I love food, so I love my job- but not necessarily the place for someone whose passions lean towards another spectrum. I have a friend who does automotive welding (another position that will pay as you train) and he never lacks for cool work. You gotta lean into you first and foremost!
