Fed chief tells Graduates

"We all know that getting a better-paying job is one of the main reasons to go to college. ... But if you are ever tempted to go into a field or take a job only because the pay is high and for no other reason, be careful!" Ben Bernanke said in his commencement address.

"Having a larger income is exciting at first, but as you get used to your new standard of living and as you associate with other people in your new income bracket, the thrill quickly wears off," he said.

Studies found that just six months after winning a large lottery prize — even in the million of dollars — people reported being not much happier than they were before winning, Bernanke said.

Other findings: Happy people tend to spend time with friends and family. Happy people tend to do what they love for a living or a hobby. Happy people tend to feel in control of their lives.
