SO glad to see someone evaluate moving jobs in this way - it just makes a whole lot of sense.  In over 30 years in IT I've moved for the right reasons and once for the wrong reason - BAD time had by my family as a result!  It's likely been said by many before, but "I work to live, not live to work" and "there are few on their deathbed who wish they could have spent more time in the office!" - I'll be one who looks back and is glad that the answers to David's questions in my life meant much happiness, less stress, respect from many peers, sufficient income and lots of fun (even at work!).

Yes, take David's questions seriously and enjoy life AND work - the two aren't mutually exclusive.
