500 yrs back, when many of us were young, "jobbe of worke" meant a forceful 'jab' at some piece of work (contrasted with continuous labor).
various societies have evolved systems of norms or enen moral codes to facilitate how and which individuals will be expected to do the necessary busy-ness to sustain a given culture.
the main function of the cultue is to provide its members with a sense of worthiness, even of heroism. so our ideas about work and career are entwined both with individual personality type as well as what others expect of us.
modernity has given some freedom to each 'worker bee' and we are able to opt out of society's business. only you know if your social compensation (pay and appreciation) is balanced with your individual self-worth. if yes, you may retire later on. if no, you have to determne your personal answer to "How much stuff is enoug?" if your answer is '"more", you too may be retiring later, but not as happily as the guy before.
if you are expecting to need to be doing this, that, and the other to be a happy retiree, i would point out that in many less frantic cultures - counter to our own - one is urged to "don't just do something, sit there.'
