If you choose a career that does not fit you,you can start over.today,growing numbers of people are changing careers or getting second starts in careers that have greater appeal to them.society no longer attaches the stigma7） of "instability" to the idea of career hopping,as it once did.motives or reasons for changing careers vary widely,but many people move because they feel stale or fed up with a grinding or dull routine.for some,a second start grows out of the realization that what they want out of life is not what they are doing,and they decide to do these things they enjoy and believe to be important.certainly,time spent in one occupation is likely to narrow the range of later occupational choices,very few people have the motivation and financial resources to start a completely new career in midlife.most people move to a related field that involves a minimum8） of new training.
