Even though my ears rang for 9 months after I quit the job (developed equilibrium problems due to the work and sleep deprivation), I was blessed to have that gig as it allowed me to be home 100% with my youngest babies and raise them myself. I wouldn't trade that for any amount of money.
Plus I developed a GREAT right arm. :-)
I sold the New York Times over the phone as a kid. I was fired for not selling ONE. But then every person I talked to would scream: “I’m not buying that commie rag!” and would slam the phone in my ear. I didn’t think I deserved to be fired.
