To all of the folks who attest that they enjoyed what they were doing, a follow-up question: did you also enjoy the area in which you were living?
Example: Billy is a petroleum engineer. Loves his job, loves the pay, loves the field-work. But Billy is based in Houston. He's a Californian through-and-through. Texas culture doesn't accord with him. Neither does the humidity. Billy has no particular desire to conclude his career, but he knows that he faces a stark dichotomy: either keep working, but be miserable outside of work... or go chase his dreams, of lifestyle and living-locale... but conclude his career, and call it retirement.
What should Billy do? Has anyone faced a predicament, like Billy's?
