FWIW, brewing is my second career. I used to be a mechanical designer working for medical laser companies in Silicon Valley. I burned out on it and ended up hating my job.
I started homebrewing and fell in love with it. So I took a job in a brewery before finding out enough to dissuade me, thankfully, because I still enjoy my work 23 years later. Sure, there's been ups and downs, and breweries that I didn't like working for, but overall it's been very satisfying work and I'm in a sweet situation now.
I realize its not for everyone, to each their own, but for me it's what I'm passionate about. And I still brew at home, because it's still fun, and is totally, completely different than brewing commercially. My lovely wife thinks I'm obsessed, I think she just needs another beer. 🍺
