Values:
Values inventories focus on what the individual feels are the most important aspects of work. Every person has a values set that needs to be reflected in a job for work to be fulfilling and rewarding. If you don't take your values into account when planning your career, there's a good chance you'll dislike your work and therefore not succeed in it. For example, someone who needs to have autonomy in his work would not be happy in a job where every action is decided by someone else.
