Interesting post by Andy Leonard.
I'll add in my two cents that you should seek happiness and
satisfaction in your job. I totally understand that people get caught
in situations, have responsbilities, obligations, and financial reasons
for taking or keeping a job, but that should be a short term thing.
Keep your eye on what makes you happy and helps you enjoy life.
And if you are stuck in a job you don't like, be sure that you make the
rest of your life better to compensate. Spend more time on a hobby,
family, take more long weekends, etc. to be sure that you don't
overload yourself with stress over a bad job.
