Research has shown that the average adult changes careers at least 3 times during their life (and often more than that). That figure makes sense when you consider how much we grow over time and that a career spans at least 40 years. Over time our values, priorities, and interests change and we often find ourselves looking for something different from our work. The career we found ourselves in during our 20s may differ greatly from where we would like to be in our 50s.
