My wife has a masters degree in marketing. She ditched the desk job to become a dog breeder. She's never going to have desk job ever again. After a few years she asked me to build online business related to it (https://www.canadapups.com). I think the key is to mix expertise. Marketing + dogs, technology + dogs, technology + coffee. If someone feels like they need to switch careers, it's probably a great idea - good chance of success in the next career due to bringing the previous careers skills to the new one.
