Choosing a career is one of the most important decisions you will make in life. It’s about so much more than deciding what you will do to make a living. To start with, think about the amount of time we spend at work. We are on the job approximately 71% of every year. Over our lifetimes, this comes to roughly 31½ years out of the 45 years most of us spend working, from the beginning of our careers until retirement. The importance of selecting a career with which we are satisfied cannot be overemphasized.
