Reference to any unique jobs that doesn’t require customer service

Could someone refer me to a website link, person, or business, where there is no customer service interaction. I am currently in the health care field right now. I am a cna and currently taking clinicals for dental assisting I don’t really like it. I am always looking out for new ways of living or occupations because I change my mind so frequently. I kinda want to do a job that is not being advertised on television or social media, that makes good money. Not too dangerous. If anyone know anything or work as such could you please comment? I am kinda tired of doing healthcare work and interacting with people.
