Would you take a job promotion?

[Powell Chee]

Currently my day job is a great one, maybe even the best I've had.   Sure I'd like to make more money but it pays well, it's flexible, not a lot of stress, I'm good at it, the commute is easy (for Los Angeles), great benefits, all good things.  Best of all I have enough of a work-life balance to enjoy life, pursue real estate investing, and build an extraordinary future with my wife (real estate investing helps a lot too).  

Well, I was just approached about a promotion at my day job. It would mean more hours and more stress, roughly $15-20k more a year, and a better career path.   The work-life balance would not be as balanced as it is now.

What would you do?
