Answer:
I feel that the given statement is false.
Step-by-step explanation:
It all depends on the company in which we work, the team, the atmosphere which we get to work and also other personal background. Any person will get satisfied with works sometimes but not always.
We cannot say that a person who has chosen his career will always be dissatisfied. So the person switches between satisfied and dissatisfied based on the situation, expectation and the resultant.
A career can be successful if there is a very good team, a good manager to encourage, a good company to pay a reasonable salary and the happiness which the person receive by doing work.
