Looking for my final "Career"

Confucius said: "Choose a job you love, and you will never have to work a day in your life."

According to Wikipedia, job hunting, job seeking, or job searching is the act of looking for employment, due to unemployment, discontent with a current position, or a desire for a better position. The immediate goal of job seeking is usually to obtain a job interview with an employer which may lead to getting hired. The job hunter or seeker typically first looks for job vacancies or employment opportunities.

My goals are a bit different... I have been very successful in many business career settings. I want to contribute back and figure I have about 15 years before I would want to consider cutting back from full time before retirement. So, I want my "last career choice" and preparation for it to be just right!
