Many People with Long-Term Goals, Such as Becoming a Doctor

Many people with long-term goals, such as becoming a doctor, eventually abandon their long-term goal pursuit.The essential motivational problem with long-term goals is that they:

A) are incompatible with implementation intentions, which are crucial for goal attainment over a long period of time.
B) focus the performer on what to do rather than on when to do it.
C) ignore the importance of key factors of performance such as coaching and training.
D) provide insufficient opportunity for performance feedback and positive reinforcement.
