I want to quit my job

Alright I’ll keep my rant short. After working insane hours for an year or so (and learning A LOT), I started exploring other jobs with better pay and work life balance. I came across model risk management (validation/governance whatever you call it) and it seemed interesting to me. I took it, and it turned out to be a big mistake. Although the pay is good, but I don’t think I’m learning even a fraction of what my previous job offered. I’ve been interviewing for the past 3 months and the extent of brain decay caused by a laid back job is getting more and more apparent. The industry expects me to have certain skills which I clearly lack now. I wish to quit my job and do something that helps me build hard skills relevant in the industry. If there is anyone who has worked in model risk management, I’d love to connect and understand their perspective.
