typically, higher salary = higher stress, more hours, difficult problems. if you want a lower stress job, go find one that pays less. either they'll expect less of you, or the problems will be easier for you to solve, so you'll not be stressed at deadlines.

this isn't always the case, of course, but its just my observation. out of college, i took a lower paying position that was very low-stress, and i had time to live my life. some friends who went into the financial sector got paid more, but were pulling their hair out and working long hours.
