Agree with several posters. I had a wonderful career full of special experiences, but nothing memorable enough to leave an imprint on the average listener/reader.
Even if you're Cronkite, Scully, Bisher, Royko or Herb Caen, somebody will wind up replacing you. Hell, Neil Armstrong was the first man on the moon and NASA found more astronauts after he retired.
Employment in any industry is a negotiated two-party deal that can be ended by either side without further obligation. I've been fired and I've left on my own terms. But I never felt the need to explain my reasons for leaving to anyone outside of the building. There were dozens of sports editors at the Rocky Mount Evening Telegram before my name showed up on the page and plenty more have taken the job in the 25 years since I left.
Don't let work define your worth as a person. But to the original post: Take the better job now, take the better life as soon as you don't need the job any more.
