An average person should expect to change careers at least once in their lifetime. Often, such a change of course happens in response to choices that go quite far back into the past. At the time, your values and interests were perhaps not aligned with those you presently hold. Our personalities constantly evolve and it is valid to want our jobs to reflect these changes. That's why so many people consider career transition. In any event, before making such a decision, it is important to take the time to assess your current situation and explore some professional options in order to choose the most satisfying path in the long-term.
