Super Theory

I agree with assumption of Super's Theory that people differ in their abilities, personalities, needs, value, interests, traits and self concepts. Because of that there are so many kind of work on this world. For example businessman, engineer, lawyer, coach, lecturer and many more. All this profession have different abilities, personalities, needs, value, interests, traits and self concepts. People choose work that match with their personalities and abilities. For example one that like about engine will choose job that require him to involve with engine such as engineer. But sometimes if one have the interest in one job but he not have abilities for that job so he cannot choose the job as their profession. Instead, he can do job that nearly similar to that job. For example if a woman have an interest to be a contractor but she do not have the abilities because of her health problem so she can choose to be a lecturer and teach about construction. Am I right?
