What makes a person successful?

I am a senior in college who will be graduating in Dec 2003  I plan to
go into the business world and I find myself pondering on what makes a
person successful in life.  I have narrowed it down to three key
things.  Having the right attitude, the right skills and setting goals
in life. Can anyone add to this or does anyone have a different idea
of what makes one successful?  If so I would love a response.
