Final answer:
Option C. The key part of changing a procrastination habit is understanding the root causes, which allows for the creation of a targeted strategy. Setting clear and attainable goals and establishing criteria to measure progress are also crucial steps in overcoming this habit.
Step-by-step explanation:
The most important part of changing a procrastination habit is C) Understanding the root causes. To effectively tackle procrastination, one must delve into the reasons behind the behavior. This includes recognizing triggers, dealing with underlying issues such as fear of failure, and learning more about one's work patterns and motivations. Only by identifying these root causes can a strategy be formed to combat procrastination.
Setting achievable and appropriate goals is pivotal as well. Goals should be clear and attainable, requiring careful planning. Taking the example of the businessman who believes hard work is a reward in itself to his desire for a raise, he may need to set the goal of actually communicating his achievements and asking for that raise, rather than just working harder in silence. Furthermore, being able to measure progress towards your goals is motivating. The criteria for success should be established so you can confidently answer the question.
