Saw this in Yahoo News, sounds quite true to me!! (about Salary and work) :

"Underestimating happiness as a factor": A higher salary generally won't make up for a job where you'll be miserable, so think carefully about factors other than money: the work you'll be doing, the people with whom you'll be working, the company culture, and even the length of your commute. It might be worth giving up a bit of extra pay to ensure that you're happy going to work every day.
