not enjoy career

salam.. i had read mohd najib wrote.. he says that enjoy your career and do what your enjoy with. i disagree with it, because not all people enjoy with thier career. i know it is truth that a good quality of productivity depends on good commitment given by a worker. but there are some people not satisfied with their jobs. for example, accauntant bank, project manager, operators.. always tension and presures with their works but they still have to go on working because thats are their career and they need it in their life.
